2.9.5 Remote OVP Sensing
The default configuration for the OVP circuit senses the output voltage at the power supply
output terminals. For applications using remote sensing where there is a need to accurately
monitor the actual load voltage, the following procedure allows the OVP sense point to be
shifted from the power supply output to the sense line connection points.
1. Shut the unit off and disconnect it from its power source. Remove the cover from
the unit.
2. Unsolder or clip out R412, the zero ohm OVP sense link located next to the output
filter capacitor C53.
3. Install a piece of insulated #22 AWG wire from the via marked C (near R412) to the
via marked C1 (near capacitor C51).
4. Reinstall the cover and reconnect the unit to its power source.
To return to local OVP sensing, remove the jumper installed in step 3 above and install a
jumper across R412 removed in step 2.
2.10 Remote ON/OFF
This feature is useful in test applications requiring remote ON-OFF control of the output. The
remote ON-OFF control circuit uses either a TTL compatible or a 12-250 Vac (or 12-130 Vdc)
input to remotely control (disable or enable) the power supply output. For TTL operation, a logic
