* Last Setting Memory.
* Independent Remote ON/OFF (opt-isolated) and Remote Enable/Disable.
* Parallel operation (Master/Slave) with Active current sharing.
* Remote sensing to compensate for voltage drop of power leads.
* Cooling fan speed control for low noise and extended fan life.
* Zero stacking- no ventilation holes at the top and bottom surface of the power supply.
* Optional GPIB interface (SCPI compatible).
* Optional Isolated Analog programming/monitoring (0-5V or 0-10V, user selectable and
4-20mA).
1.2.4 Multiple output power system
The PU power supplies series can be configured into a programmable power system of up to 31
units using the built-in RS232/RS485 communication port in the power supply and the RS485
linking cable provided with each power supply.
In a GPIB system, each power supply can be controlled using the optional GPIB controller (factory
installed).
1.2.5 Control via the serial communication port
The following parameters can be programmed via the serial communication port:
1. Output voltage setting.
2. Output current setting.
3. Output voltage measurement.
4. Output current measurement.
5. Output on/off control.
6. Foldback protection setting.
7. Over-voltage protection setting and readback.
8. Under-Voltage limit setting and readback.
9. Power-supply start up mode (last setting or safe mode).
1.2.6 Analog voltage programming and monitoring
Analog inputs and outputs are provided at the rear panel for analog control of the power supply. The
output voltage and the current limit can be programmed by analog voltage or by resistor, and can be
monitored by analog voltage. The power supply output can be remotely set to On or Off and analog
signals monitor the proper operation of the power supply and the mode of operation (CV/CC).
