The New Flagship model is born!
Introducing the new standard of Electronic Load !

High-speed response, universal interface, large-scale system compatibility
The PLZ-5W series electronic load is the successor of thehighly respected PLZ-4W that continues the series tradition ofhigh specification and excellent build quality.
New improvements include a userfriendly LCD color display and a widevoltage range from 0.25 V to 150 V.
Custom voltage/current profiles can
now be programmed using the new
ARB function, ideal for LED driver andsolar panel testing. The PLZ-5W now
includes 6 basic modes of operation(CC, CR, CV, CP, CC+CV, & CR+CV) Detachable input terminals
for ease of use.
for optimal flexibility in any test facility.
The PLZ-5W is now equipped with a high-speed responsefeature boasting a maximum slew rate of 60 A/us (PLZ1205W)
and a minimum setting resolution of 10 uA (PLZ205W).
Additional features include a soft-start function, variable slew
rate, selectable response mode (CV/CR mode), switching
function, ABC programmable memory, 20 user-defined setup
configurations, and a sequence function. The high-speed
response of the PLZ-5W is ideal for the development andtesting of modern day power supplies that require suddenchanges in current at high speeds as well as for testingof current clamps and transducers. The PLZ-5W series isavailable in 4 standard models which can be incrementally
expanded by adding booster units (PLZ2405W) for a maximumof 10.8 kW/2160 A. The PLZ-5W now is equipped with adiverse digital communication interface supporting LAN (LXI),
USB, RS232C, analog control, and GPIB as a factory option.

Functions

Operation modes

Arbitrary I-V characteristics (ARB) mode

The following five operation modes are available on the PLZ-5W.
These can be selected when the load is in the off state.

In ARB mode arbitrary I-V characteristics can be set by entering
multiple I-V points (voltage and current value set points). 3 to 100
points can be registered and the spaces between all points areautomatically linearly interpolated. This mode can be used forthe simulation of LED drivers and other DUT's with non-linear
characteristics.[P8]

Constant current(CC) mode

A current value is specified and the current is kept constant evenwhen the voltage changes.

Constant resistance(CR) mode

A conductance value is specified and the PLZ-5W sinks current
proportional to the voltage variation.

Constant voltage(CV) mode

A voltage is specified and the PLZ-5W sinks current so that thevoltage at the load input end of the PLZ-5W is constant.

Constant power(CP) mode

A voltage is specified and the PLZ-5W sinks current so that thepower consumed inside the electronic load is constant.

0.6

Arbitrary I-V
characteristics(ARB) mode

The desired load characteristics can be set by specifying multiple
arbitrary voltage values and current values as I-V characteristics.

Adjustable slew rate

Short function

The speed of change can be set when the current is changed.
The slew rate setting will function in the following instances.
●When the setting is changed to vary the current value(including the switching function).
●When the current value is changed using external control inconstant current (CC) mode.
●When the current value is changed while the load is on.

When the short function is activated, the maximum current value
will be set if in CC mode, and the minimum voltage value will be set
if in CR mode. The relay contact (30 Vdc/1 A) of the EXT CONT
connector closes, and the load imput terminals can then be shorted
by driving an external high-current relay.

The slew rate is set

for the rise and fall
speeds. In CC modeand ARB mode, theslew rate can be
set regardless ofwhether the load ison or off.

Functions

Soft start function

Remote sensing function

The soft start feature controls the rise time of the load current. The
soft start feature can be activated when the following conditions are met.
●The rise time of the soft start has been set.
●"Load on" while in CC Mode.
●Soft start input settings start from zero input and end equal to or
above the minimum operating conditions.

With remote sensing, the voltage measurement point can bechanged from the load input terminal to the DUT sensing point.
By connecting the sensing leads to the DUT, the effects of voltage
drops caused by resistance in the load cables can be reduced andthe load current stabilized. To activate remote sensing, connect thesensing cables to the sensing terminals of the PLZ-5W at the DUT
end, and enable the remote sensing function.
●Possible remote sensing compensation voltage : approx. 7 VThis function can be used if the output of the DUT becomes
unstable when the load current rises sharply, or when the operator
wishes to delay the current change on startup to prevent the DUT's
overcurrent protection circuit from being activated.

Synchronized operation

The operator can execute a long sequence of predetermined values
with the sequence function. A sequence consists of programs andsteps. A program is a collection of steps, which are executed inorder, one by one, starting from step 1. The program is considered
complete after the last step in the program is executed.

The following synchronization features are available whensimply connecting the PLZ-5W with other equipment using acommunication cable.
●Synchronizing load on/off among multiple pieces of equipment●Synchronizing measurements (remote control)●Synchronizing the start time and resume time for sequences
across multiple units
Different PLZ-5W models can be connected (Ex: PLZ205W and
PLZ1205W). Synchronization is also available during parallel

For fuse rupture tests, DC power supplies with high-speed CC current control is absolutely vital. Although it is normaly quite difficult to achieve
such high-speed control with only a DC power supply, the addition of a PLZ-5W electronic load makes high speed current control possible. With
the PLZ-5W, fuse rupture tests that adhere to standards such as the JASO D612 are made possible. These tests include voltage drop tests,

Sequence creation and control software

SD023-PLZ-5W (Wavy for PLZ-5W)
Make the Kikusui power supplies and electronic load more intelligent!
Expand the ideas of engineers with the sequence creation and control software " Wavy "[Operating environment] Windows 7 / 10

The SD023-PLZ-5W (Wavy for PLZ-5W) is an application software designed for sequence creation and operation of Kikusui’s
PLZ-5W series of DC electronic loads. It allows users to freely carry out sequence control of power supplies and electronicloads without any programming knowledge. Users can easily edit sequences as if drawing a picture or working on a
spreadsheet.
● Able to easily create and edit sequence functions using a mouse.
● Execution positions are visually displayed during sequence execution.
● Monitors voltage and current, which can be saved into files.
● Monitor data displayed in real time as a monitor graph.

Set up steps by
drawing with amouse in the graphwindow.

Set a step byinputting values
and conditionsin the sequence
window.

“Monitor graph”
Current values for current, voltage, and power canbe checked for the sequence being executed ona graph in real time. Monitor data is displayed byplacing the mouse cursor on the graph.

“Arbitrary I-V characteristics (ARB) mode”
In the arbitrary I-V characteristics (ARB) mode, desired I-Vcharacteristics can be set by specifying multiple arbitrary
points of I-V characteristics (as sets of voltage and current
values).

“Direct control window”
Directly control PLZ-5W in a manner
similar to using a remote control. In
addition, monitoring and logging of
output are also possible.
