Remote Voltage Programming Of Output Voltage And Current Limit - TDK-Lambda Genesys GEN6-100 User Manual

6.4 REMOTE VOLTAGE PROGRAMMING OF OUTPUT VOLTAGE AND CURRENT LIMIT

To maintain the isolation of power supply and prevent ground loops, use an
isolated programming source when operating the power supply via remote
analog programming at J1 connector.
Perform the following procedure to set the power supply to Remote Voltage programming :
1. Turn the power supply AC On/Off switch to Off.
2. Set setup switch SW1-1 to its UP position for output voltage external programming and
SW1-2 to its UP position for Output Current limit external programming.
3. Set SW1 position 3 to select programming voltage range according to Table 6-3.
4. Ensure that SW1 positions 7 and 8 are at their Down (default) position.
5. Connect a short between J1-8 and J1-12 (refer to Table 4-4).
6. Connect the programming source to the mating plug of J1 as shown in Fig.6-1. Observe
correct polarity for the voltage source.
7. Set the programming sources to the desired levels and turn the power supply ON. Adjust the
programming sources to change the power supply output.
NOTES:
1. SW1 positions 4,5,6 and 9 are not required for remote programming. Their setting can be
determined according the application.
2. The control circuits allow the user to set the output voltage and current limit up to 5% over
the model-rated maximum value. The power supply will operate within the extended range,
however it is not recommended to operate the power supply over its voltage and current
rating and performance is not guaranteed.
