External Overvoltage Protector

These modules can be used with any manufacturer’s power supply between 5 Vdc and 150 Vdc.

MAIN SCREEN

These Overvoltage Protectors may be used as independent accessories for any power supply to prevent the output voltage from exceeding the trip point of the protector under any condition. When triggered, the protector short circuits the power supply output, causing the LED indicator to turn off. These modules can be used on power supplies with DC voltages of 5 to 150 Vdc. They are often used to protect integrated circuits and other sensitive loads. Typical applications set the OVP trip point .5 Vdc (or +15%, whichever is greater) above application voltage.

STANDARD FEATURES
