1.2.4

Multiple output power system

TM
The Genesys 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 (fac-
tory installed).
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 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).
1.2.7

Parallel operation

TM
Genesys power supplies of the same Output Voltage and Current rating can be paralleled in a
master-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 Out-
put 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.
