Application:
Applied to provide fine over voltage protection of electronic equipment whose power is supplied by direct-current power supply.
Applied to electrical systems to provide a discharge path to earth to save those systems’ components from being exposed to the high-voltage transients caused by the direct or indirect effects of lightning or power system anomalies.
Widely used in the lightning protection of telecommunications room DC bus, the DC bus bar microwave communications room, closing the substation bus, control bus.
Installation:
When installed, in and out terminal of SPD will be corresponding connected with”+”,”-“pole of the DC power; ” PE ” is connected with grounding line;Connection way is by screwing tightly.
