1.1 Overview

Overview

1.1"LP5394" is a low noise DC power supply that achieved an output noise of 10 Vrms or lowers(typical) (10 Hz to 20 MHz bandwidth) and output voltage stability of ±10 ppm/C (typical).
The output voltage can be adjusted in the range of 0 to ±3 V, 0 to ±5 V, 0 to ±10 V, or 0 to ±15 V
using the VOLTAGE RANGE switch and adjuster on the front panel. The maximum output current is±0.1 A.

Features

1.2a)

The output noise is 10 Vrms or lower (typical) (10 Hz to 20 MHz bandwidth).

b)

The output voltage stability is ±10 ppm/C (typical).

c)

The output terminals are HR10-7R-4S (73) which is the same model as that of SA-600
Series.

d)

The output can be turned ON and OFF on the front panel.

e)

The output can be fine-tuned from 0 V to the maximum output voltage using the
VOLTAGE RANGE switch and 10-turns dial adjuster on the front panel.

f)

The output is insulated from the chassis (±42 Vpk) to eliminate the current noise caused by
the GND loop.

g)

The power input voltage can be selected from AC 100, 120, 220 and 240 V using the
VOLTAGE SELECTOR switch on the rear panel.

h)The positive and negative output voltage can be monitored using the analog meter and
POLARITY selector switch on the front panel.

i)

1.3

This is an ideal power supply for the Low Noise Amplifier SA Series.

Operating Principle

The power input voltage is insulated, reduced, and rectified by a transformer, and then converted to astable DC voltage by a series regulator. The output voltage can be adjusted in the range of 0 to ±3 V,
0 to ±5 V, 0 to ±10 V, or 0 to ±15 V using the VOLTAGE RANGE switch and adjuster on the front
panel.
The output stabilized by the regulator can be switched ON and OFF using the output selector switch
on the front panel.
The output GND is connected with the chassis GND with 10 M.
A voltage meter is available to allow for monitoring the positive or negative output using the
POLARITY selector switch on the front panel.

LP5394 Panel Component Names and Functions

See Figure 3-1 LP5394 Front and Rear Panel Views■ Front Panel① Voltage Meter
This is a 15 V full-scale output voltage meter.
② Voltage meter POLARITY
This is a switch to monitor the positive or negative output voltage. The positive and negative
voltage can monitored by setting the switch to the positive (+) and negative () side, respectively.
Applying excessive force to the switch may cause damage.
③ VOLTAGE RANGEThis switch allows you to switch the full-scale output voltage. You can select the full-scale voltage
from the four voltage range 3, 5, 10 and 15 with a screwdriver.
Using a flat-blade screwdriver whose tip does not match or applying excessive force to the switch
may cause damage.
④ OUTPUT ON/OFF LED
These LEDs indicate the ON/OFF status of the output voltage. Furthermore, if the overheat
protection function is activated, the OFF LED flashes.
⑤ OUTPUT switch
This switch allows you to switch between ON and OFF. Flip the switch up to turn on the output,
and flip it down to turn off the output.
Applying excessive force to the switch may cause damage.
⑥ OCP LED, OCP LED
When the output current is over approximately 150 mA or more, +OCP LED and OCP LED turnon with working positive or negative output over current protection function respectively.
⑦ Output connector
This is an output terminal. The connector is HR10-7R-4S (73). Applying excessive force to theconnector may cause damage.

LP5394

3.1 LP5394 Panel Component Names and Functions⑧ MONITOR terminals
These are output voltage monitor terminals (mating pin diameter 2 mm). The output resistance ofthe monitor terminals is approximately 1 k. Therefore, it is recommended to monitor the output
voltage with, for example, a multimeter with an input resistance of 1 M or more (error 0.1 %with an input resistance of 1 M and 0.01 % with 10 M).
Applying excessive force to the terminal may cause damage.
⑨ VOLTAGE ADJUST dialThis adjuster allows you to adjust the output voltage. The adjuster has a 10-turn dial which allows
you to adjust the output voltage from 0 V to the full-scale voltage set in OUTPUT RANGE. The
dial setting value of 10 outputs the full-scale voltage and the dial setting value of 0 outputs 0 V.
The minimum scale on the dial is 0.2 % of the full-scale voltage.
Applying excessive force to the adjuster may cause damage.
■ Rear Panel⑩ POWER switch
This switch allows you to turn on and off the power. Set the switch to the “I” position to turn on
the power, and set it to the “O” position to turn off the power.
Applying excessive force to the switch may cause damage.
⑪ InletThis is a connector to the outlet. Apply the power input voltage set with VOLTAGE SELECTOR.
Furthermore, one of the pins of the three-prong power connector serves as a protective grounding
terminal so is sure to connect it to an earth ground.
⑫ Fuse holder
The fuse holder holds the fuse in place.
Strictly observe the rating of the fuse (refer to 2.3). Before replacing the fuse, be sure to disconnect
the power cord.
⑬ VOLTAGE SELECTOR switch
This switch allows you to switch the power input voltage. Switch the power input voltage to theone you want to use with a Coin-driver.
Set the switch to the position where it clicks to prevent it from being in a half-way position.
Applying excessive force to the switch may cause damage.

Protection Functions and Display

3.6.1

Overcurrent Protection

If the output current of this product is over ±0.15 A, OCP LED turns on to indicate that the producthas over the rated current.
The overcurrent protection is based on a drooping characteristic of approximately ±0.15 A. If theovercurrent protection function works, the OCP LED turns on. If the output current falls below
approximately ±0.1 A, operation is automatically restored.
If the OCP LED turns on, turn off the output switch and check that the output load does not over the
rating of this product and the connection is correct.

CAUTION
Do not disconnect and connect connectors while output is on. This product or the connected load
may be damaged.

3.6.2

Overheat Protection

If the internal temperature of this product is over 75 C, the output turns off and the OUTPUT OFF
LED flashes. If the internal temperature falls below 45 C, normal operation is automatically restored.
A load short circuit over a long period of time or continuous operation at a room temperature of 50
C or more works the overheat protection function. If the overheat protection function is works, checkthat the environmental conditions and output load are within the specifications.

CAUTION
If this product is used under environmental conditions that over the specifications (0 to +50 C[day's average temperature 40 C or lower], 25 to 80 %RH [absolute humidity 1 to 25 g/m3 orlower]), this product may malfunction.
