∗
Remote sensing to compensate for voltage drop of power leads.
∗
External Analog Programming and Monitoring standard (0-5V or 0-10V, user selectable).
∗
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 Genesys
TM
power supplies series can be configured into a programmable power system of up to 31
units using the built-in RS232/RS485 communication port 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 in-
stalled).
1.2.5 Control via the serial communication port
The following parameters can be programmed / monitored via the serial communication port:
1. Output Voltage setting.
2. Output Current setting.
3. Output Voltage measurement.
4. Output On/Off control.
5. Output Current measurement.
6. Foldback protection setting
7. Over-voltage protection setting and readback.
8. Under-Voltage limit setting and readback.
9. Power-supply start up mode (Auto-restart or Safe-start 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 can be programmed by analog voltage or by resistor, and can be moni-
tored 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).
1.2.7 Parallel
operation
Genesys
TM
power supplies of the same Output Voltage and Current rating can be paralleled in a mas-
ter-slave configuration with automatic current sharing to increase power available.
1.2.8 Output
connections
Output connections are made to rear panel bus-bars for models up to 60V and to a 4-terminal wire clamp
connector for models above 60V rated output voltage. Either the positive or negative terminal may be
grounded or the output may be floated. Models up to 60VDC Rated Output shall not float outputs more
than +/- 60VDC above/below chassis ground. Models >60VDC Rated Output shall not float outputs more
than +/-600VDC above/below chassis ground. Contact factory for assistance with higher float voltage
applications.
Local or remote sense may be used. In remote sense, the voltage drop on the load wires should be
minimized. Refer to the specifications for the maximum voltage drop value.
