FS-DR-12/2.9 12 DIN rail Signal voltage surge suppressor

FS-DR12/2.9

FS-DR-12/2.9 is a 12V DC control signal surge protector designed for street wind energy systems, sensors and monitoring equipment. It guards against lightning and transient surges to ensure stable operation of outdoor wind power devices.

-Din rail signal surge protective device are applied to control signal double wire circuit in LPZ0 to LPZ3,e.g. 4~20mA circuit, RS485 circuit, RS422 circuit,gas detector, car-park system, CCTV remote monitor,remote control circuits.

-Common and difference surge protection mode, excellent performance.

-The pluggable module allows a fast replacement in case of fail.

-The grounding is realized through an earthing-clip onthe DIN-Rail and/or earthing – clamp.

-No limiting in operating current due to parallel connectingmethod.

-Mounting on 35mm Rail, small space.
