Edco PHC Series
Two-Pair Signaling Circuit Protector (Modular)
The Edco PHC Series is designed to protect two pairs of wires specifically
for alarm and security systems where operating currents can be as high
as 5 Amps. Electrically, the Edco PHC Series is a rugged series hybrid
implementing a staged complement of MOVs, copper wound inductors and
Silicon Avalanche Diodes. This design reduces series resistance to 0.2 Ohms
per pair. These products are intended to mate with an Edco PCB1B
gold-plated female terminal connector.
The Edco PHC modules plug into a base assembly (Edco PCB1B). The base
assembly can be mounted to any flat surface and should be located as close
as practical to the protected equipment. Terminal 1 and/or terminal 10
should be connected to Building-Approved Ground with 12 or 10 gauge
solid wire.
