Output overvoltage Protection

If the power supply is equipped with an overvoltage crowbar, the front panel will contain
overvoltage adjustment. The potentiometer controlling overvoltage may be adjusted
through an access hole in the front panel.
For trip levels less than the maximum output voltage or to check the overvoltage circuitry,
perform the following procedure.
a. Set the potentiometer fully clockwise.
b. Adjust the power supply output voltage to the desired trip level.
c. Slowly adjust the potentiometer counterclockwise until overvoltage is tripped.
