The Genesys power supplies series can be configured intoaprogrammable 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.
InaGPIB system, each power supply can be controlled using the optional GPIB controller
(factory installed).
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 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 (last setting or safe mode)
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 programmedby 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).
Genesys power supplies of the same output voltage and current rating can be paralleled in
master-slave configuration with automatic current sharing to increase power available.
Output connections are made to rear panel bus-bars for models up to 60V and toa4-
terminal wire clamp connector for models above 60V rated output voltage. Either the
positive or negative terminal maybe grounded or the output maybe floated. Models up to
60VDC Rated Output shall not float outputsmore than +/- 60VDC above/below chassis
ground. Models >60VDC Rated Output shall not float outputsmore than +/-600VDC
above/below chassis ground. Contact factory for assistance with higher float voltage
applications.
Local or remote sense maybe used.
In remote sense, the voltage drop on the load wires
should be minimized. Refer to the specifications for the maximum voltage drop value.
* External Analog Programming and Monitoring standard (0-5V or 0-10V, user selectable).

4. Turn the front panel AC power switch to On.
1. Turn on the output by pressing OUT pushbutton so the OUT LED illuminates.
2. Observe the power supply VOLT display and rotate the Voltage encoder.Ensure that the
output voltage varies while the VOLT encoder is rotated. The minimum control range is from
zero to the maximum rated output for the power supply model.
Compare the DVM reading with the front panel VOLT display to verify the accuracy of the
VOLT display. Ensure that the front panel VOLT LED is on.
3. Turn off the front panel AC power switch.
1. Ensure that the front panel AC power switch is at Off position and the DVM connected to the
output terminals shows zero voltage.
2. Connect aDC shunt across the output terminals. Ensure that the shunt and the wires' current
ratings are higher than the power supply rating. Connect a DVM to the shunt.
3. Turn the front panel AC power switch to On position.
4. Turn on the output by pressing OUT pushbutton so the OUT LED illuminates.
5. Observe the power supply CURRENT display and rotate the CURRENT encoder. Ensure that
the output current varies while the CURRENT encoder is rotated. The minimum control range
is from zero to the maximum rated output for the power supply model.
Compare the DVM reading with the front panel CURRENT display to verify the accuracy of
the CURRENT display. Ensure that the front panel CURRENT LED is on.
6. Turn off the front panel AC power switch.
7. Remove the shunt from the power supply output terminals.
