Optically Isolated AC Solid State Power Switches

The PD2601 is an AC Solid State Switch using optical coupling with dual power SCR outputs to produce an alternative to Optocoupler and Triac circuits. The PD2601 switches are robust enough to provide a blocking voltage of up to 600V and max surge P 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 3750V of isolation and noise immunity between rms control and load circuits. As a result the PD2601 is well suited for industrial environments where electromagnetic interference would disrupt the By Clare, Inc.
