5-3. Remote voltage programming of output voltage and current limit
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 position 1 and 2 to their UP position.
3. Set SW1 position 3 to select programming voltage range according to Table 5-3.
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 Fig 5-1 and
"3-4-1. Making J1 connections".
6. Connect the programming source to the mating plug of J1 as shown in Fig.5-1. Observe correct polarity for the
voltage source.
◆
Refer to
"3-4-1. Making J1 connections".
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.
3. When voltage programming is used, front panel and computer control (via serial communication port)
of output voltage and current are disabled.
