The OptoMOS® line of AC Power Relays use dual power SCR outputs to produce an alternative to optocoupler and Triac circuits. Tightly controlled zero-cross circuitry ensures switching of AC loads without the generation of transients.

These switches are robust enough to provide a blocking voltage of up to 800V ac peak. The input and output circuits are optically coupled to provide up to 5000VRMS of galvanic isolation and noise immunity between control and load circuits. Long life and environmental integrity make these power switches ideal for controlling a variety of AC circuits in industrial environments where electromagnetic interference would disrupt the operation of electromechanical relays.


Features & Benefits:

  • Low drive current
  • High reliability
  • Provides galvanic input to output isolation

Applications:

  • Replace electromechanical relays
  • Replace mechanical switches
  • Implement computer control of electromechanical circuits
