DC Power Supplies
PAD-LA Series
Type III, Type IV, Maximum Output Voltage (16 V to 250 V) 10 models
High Performance and High Reliability Power Supplies in various models

The PAD-LA Series are renewal version of our long seller models“PAD-L Series” as known for high performance and high reliabilityof variable DC regulated power supplies used with excellent regulators. The PAD-LA Series has polished features and performance
also it has improved the “easy to use” operation by adopting anadvanced design and we aim to establish the “Basic Power Supply” which can be used in all fields of application from the R&D ,Quality Control to the Manufacturing site.
■ Use large LED monitor withhigh visibility for 4 digits display

Adopting with the Digital display fromformer Analog type, which display
the output Voltage, and Current.
Fu r t h e r m o r e , by l o c a t i n g e a c hindication of the CV/CC and ON/
OFF operation around the display,
it can easily confirm the required
information immediately.

■ Output and Set Switch

In separate to the Power Switch ofthe unit, it has equipped the “OutputSwitch” and also the “SET Switch”
which enable to confirm the setting
value of voltage and current evenwhen the output is off.

■ Putting together of the modesetting switches
2

Improving the convenience ofoperation, we have put together allof the switches located on the upper
right area of the unit for the functionof Output, Adjusting display, variable
resistor for setting of OVP and OCP,
Setting operation mode for Analog
Remote control, one control parallel
operation (or series operation) to setfor Master or Slave unit.

■ OCP(Over Current Protection circuit)

In addition to OVP (Over Voltage
Protection circuit) function, it isequipped with OCP (Over Current
Protection circuit) as standard.

■ Output Monitoring

It is equipped with the Monitor

The Monitor Output for Output
Voltage is 0 V to approx. 10 V at 0 V
to the rated output voltage, and for
the Output Current is 0 V to approx.
1 V at 0 V to the rated output current.

■ Control Terminals

Adopting the screw less wire clamp
for the control terminal block on therear panel that was used to be theharmonica terminal.

Computer Control
By using optional controller Model PIA4810, the PAD-LA Series can be controlled through by the computer.
Note: It is required for the modification of replacing ROM in case of using controller Model PIA3200.

*1: Voltage and current knob on the front panel can vary the output.
*2: It can be changed by Setting Switch for controlling the “0 to rated value/
10 KΩ to 0 Ω” from the normal setting of “0 to rated value/0 Ω to 10 kΩ”.
*3: The Setting Switch can change. The Output OFF for using contact open
as it is normally used for Output OFF by contact short.

*4: It can be changed for contact open shut off by modification as it is normallyshut off by contact short.
*5: Master/Slave configuration can be used for the same rated output model(Series Operation: Up to 2 units for 250 V model, up to 3 units for othermodels, Parallel Operation: up to 3 units)3
