The CPC1943 is an AC Solid State Switch using

optical coupling with dual power SCR outputs to

produce an alternative to optocoupler and Triac

circuits. The CPC1943 switches are robust enough to

provide a blocking voltage of up to 400V

tightly controlled zero cross circuitry ensures switching

of AC loads without the generation of transients.

The input and output circuits are optically coupled

to provide 3750V

between control and load circuits. As a result the

CPC1943 is well suited for industrial environments

where electromagnetic interference could disrupt the

operation of electromechanical relays.
