CAUTION

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.

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.
