Variable Regulated DC Power SupplyPAD-LA Series
Succession of achievements and trust
The PAD-LA Series are renewal version of our long seller models “PAD-L Series” as known for high performance and high reliability of variable DC regulated power supplies used with excellent regu-lators. The PAD-LA Series has polished features and performance also it has improved the “easy to use” operation by adopting an advanced 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.
Features
Computer Control
By using optional controller Model PIA4810, the PAD-LA Series can be controlled through by the computer.
*It is required for the modification of replacing ROM in case of using controller Model PIA3200.

- C.V. Control by external resistor *2
- C.C. Control by external resistor *2
- Output ON/OFF by external contact *3
- Power Switch shut off by external contact *4
- *1 Voltage and current knob on the front panel can vary the output.
- *2 It can be changed by Setting Switch for controlling the “0to rated value/10KΩ to 0Ω” from the normal setting of “0 to rated value/0Ω to 10kΩ”.
- *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 normally shut off by contact short.
Various functions
- Series Operation (One control: Master/Slave configuration) *5
- Series Operation (One control: Master/Slave configuration) Parallel Operation Parallel Operation (One control: Master/Slave configuration) *5
- Remote Sensing function
- OVP (Over Voltage Protection circuit)
- OCP (Over Current Protection circuit)
- OCP (Over Current Protection circuit)
- Output Voltage monitor (0V to 10V)
- Output Current monitor (0V to 1V)
- *5 Master/Slave configuration can be used for the same rated output model (Series Operation: Up to 2 units for 250V model, up to 3 units for other models, Parallel Operation: up to 3 units)
Use large LED monitor with high visibility for 4 digits display
Adopting with the Digital display from former Analog type, which display the output Volt age, and Cur rent. Furthermore, by locating each indic ation of the CV/CC and ON/OFF operation around the display, it can easily conf irm the required information immediately.
Output and Set Switch
In separate to the Power Switch of the unit, it has equipped the “Output Switch” and also the “SET Switch” which enable to confirm the setting value of voltage and current even when the output is off.
Putting together of the mode setting switches
Improving the convenience of operation, we have put together all of the switches located on the upper right area of the unit for the function of 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 set for Master or Slave unit.
Control Terminals
Adopting the screw less wire clamp for the control terminal block on the rear panel that was used to be the harmonica terminal.
OCP (Over Current Protection circuit)
In addition to OVP (Over Voltage Protection circuit) function, it is equipped with OCP (Over Current Protection circuit) as standard.
Output Monitoring
It is equipped with the Monitor Output Terminal for Output Voltage and Output Current as standard. The Monitor Output for Output Voltage is 0V to approx. 10V at 0V to the rated output voltage, and for the Output Current is 0V to approx. 1V at 0V to the rated output current.
