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 electromechanical relays.
