Clare Releases Single Pole Solid State Relay With Built In Current Limiting Circuitry
Clare, Inc., a wholly owned subsidiary of IXYS Corp., announced the immediate production release of the CPC1560, a fast actuating, current limiting, normally open, 1-Form-A, optically isolated OptoMOS® Solid State Relay (SSR) solution that replaces electromechanical devices and enhances system robustness.
The CPC1560 incorporates active current limit and thermal shutdown circuitry for improved survivability in harsh environments, and is designed to pass regulatory voltage surge requirements when provided with appropriate over voltage protection circuitry. The device provides 3750Vrms of input to output isolation. The device is said to be designed specifically for environmentally demanding ac or dc applications, where printed circuit board space is at a premium and additional power supplies are not available.
The 60V CPC1560 also features fast turn-on of loads up to 600mADC in a dc-only configuration or 300mArms in an ac-dc configuration. Fast turn-on (100usec) and turn-off (400usec) is accomplished with the use of an external charge storage capacitor that provides the necessary charge required by the internal switching MOSFETs. The CPC1560 charges this capacitor through bootstrap diodes from the load voltage, thereby alleviating the need for an additional power supply.
The CPC1560 OptoMOS SSR is now available in sample and production quantities with a lead-time of six weeks after receipt of order. This current limiting 1-Form-A normally open SSR is for general industrial control and instrumentation switching applications as well as peripherals, security and medical equipment. Additional key features include linear ac-dc operation, low power consumption, clean, bounce free switching and low power drive requirements.
