Description
The CPC1972 is an AC Solid State Switch using
optical coupling with dual power silicon controlled
rectifier (SCR) outputs to produce an alternative to
optocoupler and Triac circuits. The CPC1972 switches
are robust enough to provide a blocking voltage
of up to 800VP . 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 the control and
load circuits. As a result the CPC1972 is well suited
for industrial environments where electromagnetic
interference could disrupt the operation of
