Description
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.
