The PS1201 uses optical coupling with dual power SCR outputs to produce an alternative to optocoupler and Triac circuits. And its input and output circuits are optically coupled to provide 3750Vrms of isolation and noise immunity between control and load circuits. Therefore, the PS1201 is suited for industrial environments where electromagnetic interference would disrupt the operation of electromechanical relays.
Powerfully built to provide a blocking voltage of up to 400VP and a max surge current rating of 20A.
Tightly controlled zero-cross circuitry ensures the switching of AC loads without the generation of transients.
Input and output circuits are optically coupled to provide 3750Vrms of isolation and noise immunity between control and load circuits.
