Programming
To set the OVP trip level with a 0-5Vdc or a 0-10Vdc external voltage source:
OVP with an
1. Ensure the power supply is turned OFF and that both the AC power source and

Source
2. Set the power supply's internal switch SW1-7 OPEN. Ensure switch SW1-6 is
3. Connect the external voltage source between pin 3 (positive) and pin 12 (return)
4. Set the external programming source voltage to maximum (5 Vdc or 10 Vdc).
5. Turn the power supply ON and turn the front panel voltage control clockwise
6. Slowly reduce the external programming voltage until the red OVP LED lights
Note:When OVP is programmed by an external voltage source, the OVP set point
can be approximated using the following formula:
where:
