The Electrical Appliance & Material Safety Low (Japan), UL (U.S.A.), CSA (Canada), VDE (Germany) and BS (U.K) are some major examples of safety standards
in use throughout the world that require the performing of hipot testing. For this reason, it is necessary to confirm for what portion of what standard testing is tobe performed when purchasing a hipot tester. Although the 500 VA capacity hipot testers available from KIKUSUI can basically be applied to tests specified in all
safety standards, we recommend that you consult with us prior to purchase in order to select the model that best matches your specific application.

For the withstanding test and the insulation resistance test of the EUT (Equipment Under Test) with turned on electricity.
Our Hipot Testers and Insulation Resistance Testers are designed to test the EUT (Equipment Under Test) with its electricity swithedoff. In case the test requires the EUT (Equipment Under Test) with the electricity turned on, please contact with our distributor or agent.

AC Hipot Testing with Stable Output [Input Voltage Variation: ±0.3%]
Conventional hipot testers utilize a slide transformer to output ACline voltage. This design is susceptible to input voltage fluctuation,with outside electrical influence affecting the test results. This canresult in distorted voltage being applied to the EUT which can cause
product malfunctions down the line due to component malfunction.
The TOS9300 series utilizes a highly efficient PWM amplifier capableof stable high-voltage output that is unaffected by changes in the
AC power line. The TOS9300 series allows for safe, stable, and highly
reliable tests regardless of AC power line instability.

Contact/Protective Conductor/Patient Leakage Current Test (TOS9303LC)
The TOS9300 series can conduct leakage current (patient current)
tests for highly sensitive medical devices. Measurement networks
can be easily configured via the front panel. (See Applications P8,
Specifications P19)
All Electrical Safety Standard Tests inOne Device! (TOS9303LC)
The TOS9303LC is the "all-rounder" model which supports AC/DC
withstanding voltage, insulation resistance, AC/DC earth continuity andleakage currents tests in a single device. It can also be used for contact
current, protective conductor current and patient leakage current tests.
Programmable Detection Response Speed
Conventional withstanding voltage testers are generally used toonly detect insulation breakdown, and cannot make judgements on
instantaneous discharge currents like partial discharge. However,
the TOS9300 series is equipped with 5 levels of response speed
settings to accurately detect low levels of insulation breakdown.
Small discharges not visible to conventional withstanding voltage
testers are easily detected with the TOS9300 series.
Value

Description

LPF

Mean-value response type current detector. This is similar to the current
detection response of Kikusui's general-purpose AC withstanding voltage
testers. This setting is suitable for detecting dielectric breakdown defined insafety standards and for general hipot tests for general electronic devices andcomponents. This setting is not recommended for detecting corona discharge,
which is not considered dielectric breakdown by typical safety standards.

Slow

HPF

A discharge feature enables discharge of electrical energy from the
DUT after DC hipot and insulation resistance tests have completed.
The setting range for discharge time is between 0.0s - 100.0s.
AC/DC Earth Continuity Testing up to 40 A
Cut ting edge amp technology allows for a wide range ofapplications, including general AC earth conduction testingand EV/PHV system DC earth continuity testing. This also allows
for strict adherence to automotive DC standard requirements;
expected to increase in the near future.
EARTH FAULT Protection
Mistakenly changing the grounding (GND) setting to "guard"(floating) can result in grounding the test subject which can resultin unwanted leakage current emissions from the high voltage
output site into the grounding site, resulting in electric shock to
the operator. The EARTH FAULT protection function blocks output
and terminates the test; eliminating any risk of electric shock andmaximizing safety for the operator.
Offset Cancel
The Offset Cancel feature allows the user to eliminate electricalcurrent found in the insulation resistance and stray capacitanceamong the output cables (only resistance for DC testing). Thisfeature is available in all testing modes for AC withstanding
voltage, DC withstanding voltage, insulation resistance, earth
continuity and electrical current leakage tests.
Rise Time/Fall Time Control Function
The rise time control function prevents unnecessary stress frombeing applied to the EUT.
● Rise Time control function● Fall time control function

The rise time control feature allows
you to gradually increase voltage to a
set value while AC/DC hipot tests are
conducted.Voltage rise times can be set
from 0.1s to 200.0s at a resolution of 0.1s.

The fall time control feature allows you togradually decrease the test voltage after asuccessful AC/DC hipot test. The voltage
fall time can be set from 0s to 200s at aresolution of 0.1s. (OFF is also selectable).

Medium Mean-value response type faster than SLOW setting. Upper limit judgement
Fast

detection is much faster, suitable for withstanding voltage tests on compact
electronic components and other EUTs prone to dielectric breakdown.
Instantaneous discharges such as corona discharges with high frequencies aredetected which may not be suitable for simple withstanding voltage tests.

Slow
Fast

Extremely small discharges such as corona discharges are detected but withlow reproductibility.

Basic Memory Function

In addition to automatic testing memory functions, up to 51 basic
setting conditions and testing modes can be selected and saved
to the main unit or USB memory. Easy testing with no hassle!

*1 When tests are performed consecutively, output time limit and rest time may become necessary depending on the upper limit setting*2 If an AC voltage is applied to a capacitive load, the output voltage may rise higher than at no load depending on the load capacitance. Further, waveform distortions may occur if an EUT whose
capacitance is dependent on voltage (for example, an EUT that consists of ceramic capacitors) is connected as the load. However, if the test voltage is 1.5 kV, the effect of a capacitance of 1 000 pF or
less can be ignored. Because the product’s high-voltage power supply uses the PWM switching method, if the test voltage is 500 V or less, the switching and spike noise proportions are large. The lower
the test voltage, the greater the waveform is distorted.

GND is connected to Guard. Measures only the current flowing through the low terminal (current flowing through the chassis is notmeasured) (high sensitivity, high accuracy measure-ment applications).

*1 Monitor signal output is isolated from the chassis (earth). If you connect an oscilloscope or an external device whose BNC shield is grounded, be sure to set the grounding mode (GND) to Guard. The
value is not calibrated.
*2 If there is a possibility that the EUT or tools and the like will be grounded or if you are uncertain, do not set GND to Guard. Doing so is extremely dangerous because the ammeter will be shorted andwill not be able to measure current. For normal applications, set GND to Low.

*2 Humidity: 70 %rh or less (no condensation), when there is no interference caused by wobbly test leads or other problems.
*3 If the grounding mode (GND) is set to low in a highly humid environment, leakage current to ground will be generated from the high-voltage wiring sections inside the product and the high-voltage
wiring sections between the product and the EUT. This leakage current ranges from several nA to several tens of nA depending on the usage and wiring conditions of the optional TOS9320 high-voltage
scanner and greatly affects measurement accuracy. The effects of leakage current can be reduced by making measurements with the offset enabled.
*4 Add 10 % to the accuracy when measuring 100 V or less.
*5 Add 5 % to the accuracy when measuring 100 V or less.
*6 When the measured current is limited to 100 nA or more (no condensation) when the humidity is 50 %rh or less, no external disturbance is present such as swinging test leads, and the offset is enabled.

A low-pass filter can be inserted into the ammeter measurement circuit. *2*1 If there is a possibility that the EUT or tools and the like will be grounded or if you are uncertain, do not set GND to Guard. Doing so is extremely dangerous because the ammeter will be shorted andwill not be able to measure current. For normal applications, set GND to Low.

PWM switching
If the output voltage exceeds ±(10 % of setting + 0.05 kV), the output is turned off, and the protection function is activated.

*1 If an AC voltage is applied to a capacitive load, the output voltage may rise higher than at no load depending on the load capacitance. Further, waveform distortions may occur if an EUT whose
capacitance is dependent on voltage (for example, an EUT that consists of ceramic capacitors) is connected as the load. However, if the test voltage is 1.5kV, the effect of a capacitance of 1 000pF or lesscan be ignored. Because the product’s high-voltage power supply uses the PWM switching method, if the test voltage is 500 V or less, the switching and spike noise proportions are large. The lower thetest voltage, the greater the waveform is distorted.

New low-cost standard model that provides
thorough operability, reliability and safety.
The “TOS5300 Series” is a series of test instruments used in Hipot
tests and insulation resistance tests, two of the four tests regarded asnecessary for ensuring the safety of electrical products. With an output
of 5 kV/100 mA (AC) and 6 kV/10 mA (DC), the series can be usedin Hipot & insulation resistance testing of electronic equipment andelectronic parts, based on the requirements of IEC, EN, UL, VDE, JIS,and other international safety standards and the Electrical Applianceand Material Safety Law. Also, the test voltage stability is improved
with the adoption of a newly developed switching amplifier. Since theoutput voltage can be kept constant even when the AC line voltage or
frequency changes, consistent testing can be performed, even when the
power supply environment is in an unstable region. The TOS5300 isalso equipped with a number of features that are capable of meeting avariety of test needs. It is a new low-cost standard model that provides
thorough operability, reliability and safety.

Hipot Tester/Hipot Tester with Insulation Resistance Test

Basic performance
The achievement of AC Hipot testing with a constant stable
output! [ Input voltage variation : ± 0.3%]
A conventional Hipot tester boosts and outputs the AC line's
input voltage through the use of a slide transformer. With thisslide transformer system, input voltage fluctuations will affectthe output, preventing tests from being performed properly. At
times, the application of distortion voltage applied to the EUT
may cause a failure of new product (accelerating a deteriorationof components). Since the TOS5300 Series equips with a highefficient PWM amplifier that can output a stable high-voltage
without being affected by the variation of AC power line, users
can perform "safe", "stable", and highly "reliable" tests withconfidence, even in regions with large voltage variations.

Realizing high-precision measurement with high-resolution
and high-speed judgement

Protection cover prevents physical operation error in the
production site

Equipped with a high-accuracy, high-resolution of True RMS
measurement circuit, including a Voltmeter with ±1.5 % of reading(500 V or greater) / minimum resolution of 1 V, and an Ammeterwith ±1.5 % of reading (1 mA or more) / minimum resolution of
1µA. In addition, it is also equipped with an Auto range function,with achieving a judgment accuracy of ±1.5 % of reading. The
Lower limit judgment accuracy achieves a level of performanceequivalent to the Upper limit judgment accuracy that enables
to detect for such a poor contact or disconnections of test leads.
Moreover, it realizes the fast judgment by the test time of 0.1
second, while reliable testing can be performed, thanks to highprecision, high-resolution, high-speed measurement and thejudgment functions.

In many cases, workers on electronic equipment production lines
and inspection lines are not technical experts. Therefore, it ispossible that the operators may change setting conditions andmake operation errors. In order to prevent from such cases, the
TOS5300 is equipped with a key lock function and a protection
cover to disable a physical key operation from the front panel.

Reduction of the tact time leads to improve the productivity.
However, it has been an issue that reducing the tact time may
cause to worsen the measurement accuracy when the test time
is faster than the measuring response speed. The TOS5300 series
has been achieved to set the test time from 0.1s.

New design of output terminal improves safety and functionality
In consideration of safety for the operator and the environment,
the output terminal of HIGH -side has been placed in themost distant location from the control area. The free rotation
machanisim protects from twisting (or breaking) of the cable.
Also, with having the lock function for the LOW terminal on themain unit, the metal plate is no longer attached to the test lead of
LOW-side, and it makes to resist damage to the test lead. Becauseof elimination of these projected components, the TOS5300 can
avoid from unexpected accidents such as when the unit travels
to other location. And also when the test lead is snagged onsomething, or unexpected stress is applied on the test lead, theHigh (High-voltage) test lead is designed to disconnect easily, but
the Low (ground) test lead is designed to resist disconnection.
In order to prevent the insertion error, the color coding of thecable are classified to HIGH (red) and LOW (black) , and the plug
shape of terminal are also different design.

Accuracy*1: Regarding the output time limits:
Taking size, weight, and cost into consideration, the heat dissipation capability of the voltage generator that is used for hipot tests has been 		designed to be one half that of the rated output. Use the TOS5300 Series within the following limits. If you use the product in a manner that 		
exceeds these limits, the output section may overheat, and the internal protection circuits may be activated. If this happens, stop testing, and 		
wait until the TOS5300 Series returns to its normal temperature.

Waveform distortions may occur if an DUT whose capacitance is dependent on voltage (for example, an DUT that consists of ceramic capacitors) isconnected as the load. However, if the test voltage is 1.5 kV, the effect of a capacitance of 1000 pF or less can be ignored.Because the product’s 		
high-voltage power supply uses the PWM switching method, if the test voltage is 500 V or less, the switching and spike noise proportions 		are large. The lower the test voltage, the greater the waveform is distorted.
*3: For both True rms and Mean-value response, 50 ms or above response time is required to satisfy the measurement accuracy.
*4: Regarding ammeter and judgment accuracy:
During AC hipot tests, current also flows in the stray capacitance of items such as the measurement leads and jigs. This current that flows in thestray capacitances is added to the current that flows in the DUT, and the sum of these currents is measured.Especially if you want to perform
judgments with high sensitivity and accuracy, it is necessary to consider methods to limit the current that flows in these stray capacitances, such as 		by adding upper and lower limits.

TOS5200(ACW)The low cost of “New standard AC Hipot tester”
with high-usability, reliability, and safety aspect.
TOS5200 is designed for AC Hipot Test with 500 VA capacity and 200
mA short circuit current output capability. Equipped with the PWM
amplifier, the TOS5200 can provide a stable & reliable output without
being affected by AC power line. Thus, it is a perfect solution forelectronic equipment or devices complied to IEC, EN, UL, VDE andJIS etc. requirement. The TOS5200 covers most of features of which
our upper class model of the AC Hipot Test, it achieves the superb cost
/ performance ratio for those who need 200 VA or 500 VA capacity, orboth. Also, it equips the Interlock function together with other safety
features, the operator can carry out the test with higher current value insafe.

TOS5200 SERIESAC Hipot Tester

Basic performance
Highly stable output is realized with PWM Switching Amplifier!
Equipped with the PWM switching amplifier system, the TOS5200 realizes
highly stable output not affected by input form AC line.A conventional
Hipot Tester boosts and outputs the AC line's input voltage using a slide
transformer system and which, the input voltage fluctuations will affectthe output, preventing test from being performed properly. Since the
TOS5200 equips with a high-efficient PWM amplifier that can output astable high-voltage without being affected by the variation of AC powerline, users can perform "safe", "stable", and highly "reliable" tests withconfidence, even in regions with large voltage variations.

The output waveform is essential factor in Hipot (Withstanding oltage) testing!

▲ AC output waveform of TOS5200

Capable of Test Time setting from 0.1s, which enables to reduce the tact time !
The TOS5200 can set the test time from 0.1 sec without sacrificing
measurement accuracy. Reduction of the tact time leads to improve theproductivity, so it has been an issue that reducing the tact time may
cause to worsen the measurement accuracy when the test time is fasterthan measurement respond speed.

▲ AC output waveform of the slide
transformer system

Cycle timeminimize to

0.32 sRise time / Fall time control function
The rise time control function is to prevent the excessive stress thatis being applied to the EUT (test object). The Hipot ( Withstanding
voltage) test is conducted to verify the safety performance of the EUT
and which test voltage for Hipot (Withstanding voltage) test is applied
approximately five to ten times greater than the voltage that handles
by the EUT. If a high voltage is applied rapidly with no rise time, thetransitional large voltage (current) will be occurred, and it may cause
a damage to the EUT. For this reason, safety standards stipulate theprocedure of Hipot (Withstanding voltage) test, and the test voltage
must be gradually increased to the specified voltage when the test
is performed. The rise time control function adopted in the TOS5200
can set the voltage rise time from 0.1s to 10.0s (at a resolution of 0.1s)
and also it is capable to set the 50% (fixed) of the applied test voltage.
In addition, the fall time control function enables to decrease the test
voltage gradually after the completion of a PASS judgement. The voltage
fall time is fixed at 0.1s (OFF is also selectable).

*1: Regarding the output time limits: Taking size, weight, and cost into consideration, the heat dissipation capability of the voltage generator that is used for withstanding voltage tests has been designed to be
one half that of the rated output. Use the TOS5300 Series within the following limits. If you use the product in a manner that exceeds these limits, the output section may overheat, and the internal protection
circuits may be activated. If this happens, stop testing, and wait until the TOS5300 Series returns to its normal temperature.

Output time

Continuous output possible(Output time = voltage rise time + test time + voltage fall time)*2: Regarding the test voltage waveform:
Waveform distortions may occur if an DUT whose capacitance is dependent on voltage (for example, an DUT that consists of ceramic capacitors) is connected as the load. However, if the test voltage is 1.5 kV,
the effect of a capacitance of 1000 pF or less can be ignored.Because the product’s high-voltage power supply uses the PWM switching method, if the test voltage is 500 V or less, the switching and spike noise
proportions are large. The lower the test voltage, the greater the waveform is distorted.
*3: For both True rms and Mean-value response, 50 ms or above response time is required to satisfy the measurement accuracy.
*4: Regarding ammeter and judgment accuracy:
During AC withstanding voltage tests, current also flows in the stray capacitance of items such as the measurement leads and jigs. This current that flows in the stray capacitances is added to the current thatflows in the DUT, and the sum of these currents is measured.Especially if you want to perform judgments with high sensitivity and accuracy, it is necessary to consider methods to limit the current that flows inthese stray capacitances, such as by adding upper and lower limits.

PID Insulation Tester

To evaluate the PID* effect of the PV module!

TOS7210S(SPEC80776)(IR)The tester that evaluates the PID effect of the PV
module precisely and efficiently.
The PID insulation tester (TOS7210S) is designed based on the insulation
resistance tester (TOS7200) to carry out the evaluation of the PID (Potential
Induced Degradation) effect of the PV module precisely and efficiently.
Being equipped with the output ability of 2000 V and the ammeter with nA
resolution as well as a polarity switching function, the TOS7210S is also
applicable not only to the PID evaluation but also the evaluation of the insulators that requires a high sensitivity of measurement. The tester is equippedwith the panel memory that is externally accessible and the RS232C interface is also equipped as standard that can be flexibly compatible with theautomated system.

● Capable of arbitrary setting of the output
voltage● Polarity switching function● The output is floating from the ground● Analog output terminal● Equipped with RS232C as standard[PID effect]

The PID effect is a phenomenon that the amount of power generation by a cell remarkably decreases whenhigh voltage is applied between the solar cell and the frame for long hours. It is supposed that the higher theapplied voltage is and/or the higher and more humid the environment is, the further deterioration accelerates.

TOS6210

Test up to 60 A is possible!
While inheriting the basic performance and functions of its
predecessor (TOS6200), such as a constant current driving
system that provides current waveforms with little skew andhigh measurement accuracy, the TOS6210 tester extends the
maximum test current from 30 A to 60 A, which is demandedby the new standard. In addition, the tester also lets you judge
the acceptability of the device under test based on the drop
in voltage, as required in the standard. What's more, you canpreset test conditions of up to 20 different types of safety
standards, such as those for information technology equipment, home appliances, medical devices, and measuring instruments, in the memory on the main unit's panel.
A simple memory call operation allows you to set up a protective earth or protective bonding continuity test as stipulated in UL and other relevant specifications including IEC
and JIS standards. The tester also features a set of functions
that meet the specific needs of testing personnel, such as anoffset cancellation function and a memo function that allows
you to input calibration dates, production numbers, and othertest-related information and read the input information later
via the GPIB or RS232C interface.

Use of the constantcurrent method eliminates the need to reset test currents even in theface of fluctuating resistance values for the device being tested. The
test duration can also be set from 0.3 s, making the tester suitablefor production line testing, which requires reduced cycle time. This
tester is also designed for ease of use, featuring a large, easy-to-readdisplay, memory capacity for storage of 100 types of test conditions,and incorporation of test conditions into programs to enable automatic
testing. The standard equipped GPIB and RS232C interfaces allow
the user to use PCs or other devices to control test conditions such as
test current, resistance value for judgement, and test duration, and enables read-back of measured values and test results.
