CPC1943G

DS-CPC1943G-R1

The CPC1943G is an AC Solid State Switch using optical

coupling with dual power SCR outputs to produce an

alternative to optocoupler and Triac circuits. The

CPC1943G switches are robust enough to provide a

blocking voltage of up to 400V. In addition, tightly con-

trolled zero cross circuitry ensures switching of AC loads

without the generation of transients. The input and output

circuits are optically coupled to provide 3750V of isolation

and noise immunity between control and load circuits. As

a result the CPC1943G is well suited for industrial envi-

ronments where electromagnetic interference could dis-

rupt the operation of electromechanical relays.
