CPC1976 is an AC Solid State Switch utilizing
dual power SCR thyristor outputs. This device also
includes zero-cross turn-on circuitry and is specified
with a blocking voltage of 600VP .
In addition, tightly controlled zero-cross circuitry
ensures low noise switching of AC loads by
minimizing the generation of transients. The optically
coupled input and output circuits provide 3750Vrms of
isolation and noise immunity between the control and
load circuits. As a result, the CPC1976 is well suited
for industrial environments where electromagnetic
interference would disrupt the operation of plant facility
communication and control systems.
