• Please see enclosed "Terms & Conditions and Sales & Policies & Procedures"
This unit is to be used on any Sola Silver Line Linear Power Supply where there is no factory provided
Overvoltage Protection (OVP) built into the output. (Generally, all +/-5V outputs come with built-in OVP).
These OVPs can be used on any power supply with built-in overload/short circuit protection that will not
allow the current to exceed the maximum current rating of this OVP. Please note that only the Silver Line
of Sola Power Supplies have mounting holes designed for these OVPs.

The above table indicates Sola's recommended trigger voltage set point for different output voltages.
Where +/-Outputs exist with a common terminal, a single OVP module located across the positive (+)
and negative (-) terminals will provide functional OVP for both individual outputs.
The OVP module comes complete with mounting hardware and hookup leads. To connect the OVP
to your Silver Line Series Power Supply, see your Power Supply User's Manual for the recommended
placement. Attach the black lead to the negative (-) terminal of the supply and the white lead to the
positive (+) terminal. Make sure to check the positive (+) and negative (-) leads of the supply are
connected to the (+) and (-) leads of the OVP module. Rotate the potentiometer (R1) on the OVP
module completely counter clockwise. Without your load(s) connected, apply power, then adjust the
output voltage on the supply. Adjust to the level at which you wish the OVP to trigger. Slowly adjust (R1)
on the OVP module clockwise until the output of the supply drops suddenly. Remove the input power to
the supply and back the potentiometer (R1) on the OVP module slightly counter clockwise. 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 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.
Under all conditions, removal of input power is necessary to reset the OVP.
