Description
The PS1201 is an AC Solid State Switch using optical coupling with dual power SCR outputs to produce an alternative to optocoupler and Triac circuits. The PS1201 switches are robust enough to provide a blocking voltage of up to 400VP and max surge current rating of 20A. 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 PS1201 is well suited for industrial environments where electromagnetic interference would disrupt the operation of electromechanical relays.
