The CPC1945G is an AC solid state relay with zero-crossing detection, designed for low-EMI switching of AC loads up to 1 A rms at 120 V rms. It features optically isolated input and output circuits providing 3750 V rms isolation, with a 400 V peak blocking voltage and a typical on-state voltage drop of 1.6 V at 1 A rms. The device uses a 4-pin DIP package with a body size of 19.202 mm × 7.620 mm and is UL recognized and CSA certified. It operates with 5 mA control current and is rated for industrial environments with an operating temperature range of -40 to +85 °C.
The OptoMOS® line of power products uses dual power SCR outputs to produce an alternative to optocoupler and Triac circuits. These switches provide a blocking voltage of up to 800V. 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 up to 5000Vrms of 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. Load Currents up to 5 A Voltage Controlled Devices Available Blocking Voltage from 400 V to 800 V 5 mA Drive Input Sensitivity Zero-Crossing Detection Dc control and ac output Optically Isolated I/O TTL and CMOS Compatible Low EMI and RFI Generation High Noise Immunity
