Solder the black lead to the – lead of the supply and the white lead to the + output of
the supply. Double check to be sure that the + output of the supply is connected to
the + lead of the OVP module and the – output is connected to the – lead. Rotate the
potentiometer (R1) on the OVP module completely clockwise. Without having your
load connected to the supply, apply power to the supply and adjust the output
voltage on the supply, to the level at which you wish the OVP to trigger. Slowly
adjust R1 on the OVP module counterclockwise to the point at which the output of
the supply drops suddenly. The OVP trip level is now set. Remove input power to
the power supply and back the voltage adjust potentiometer slightly. Re-energize the
supply and adjust the output voltage to the nominal voltage rating. The OVP trip
level is now set. You may wish to set the OVP potentiometer in place with an
electrical grade varnish such as glyptol.
Your load is now protected against an overvoltage condition that could destroy the
load.
Should you experience a situation where the OVP triggers, remove input power!
Check for any failures.
If the input fuse to the power supply is blown, it is a good indication that there is a
failure to the power supply itself.
If you find that there is no failure, re-energize the supply. If the supply voltage
returns to nominal, the power supply and OVP will be ready for another OVP
situation. This is called a nuisance trip. It is not uncommon and does not indicate a
failure of the OVP module. Instead, it has done its job and protected your circuit.
Nuisance tripping is generally caused by voltage spikes created by the load. If it
continually occurs, check your load for noise generating conditions and correct them.
