Units
VP
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 400VP . In addition,
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 3750Vrms of isolation and noise immunity
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.
