The CPC1945G is an AC Solid State Relay (SSR)
using patented waveguide coupling with dual power
SCR outputs to produce an alternative to optocoupler
and Triac circuits. The 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
CPC1945G is well suited for industrial environments
where electromagnetic interference could disrupt the
operation of electromechanical relays.
