800V AC power switch features 5kV of isolation
Utilising dual power SCR outputs, IXYS Integrated Circuits Division has announced the CPC1964B AC solid state switch. Typical applications include programmable controls, power control panels, remote switching, gas pump electronics, powerline communication, powerline control and power meters.
This device includes zero-cross turn-on circuitry and is specified with a blocking voltage of 800Vp. The tightly controlled zero-cross circuitry ensures low noise switching of AC loads by minimising the generation of transients.
The optically coupled input and output circuits provide 5000Vrms of isolation between the control and load circuits. As a result, the CPC1964B is well suited for industrial environments where electromagnetic interference would disrupt the operation of plant facility communication and control systems.
The 8-pin power SOIC enables 800Vp of blocking voltage and 5kV of isolation; 12.5mm of external creepage distance can be achieved with the appropriate layout. The CPC1964B is approved to UL508 for general loads. The approval allows for operation at 1.5Arms on AC lines rated of 20-280Vrms.
