    Lambda - L-20-OV-20 - Overvoltage Protector.

    The L-20-OV Series of Overvoltage Protectors are hybrid devices designed to prevent damage to a load caused by excessive power supply output voltage. Load protection is accomplished by effectively short circuiting the output terminals of the power supply when the trip point is exceeded. The L-20-OV is reset when s power to the overvoltage protector is interrupted and its case temperature has fallen below 71°C. An external heatsink is required to maintain case temperature below rated limit.

    The L-20-OV Series is available for nominal supply voltages from 5 to 30 volts. The trip point voltage is fixed and cannot be adjusted. This two terminal device is available in a hybrid with an isolated flange.

    20V, Trip 22.8V +/- 0.7V

    On State Current; 20 A

    On State Voltage: 1.75V

    Non Repetitive Peak Surge Current: 260A
