Clare Expands Power Relay Family by Offering 600V, 3A 1-FORM-A, Opto-SCR Semiconductor IC with Zero Crossing Circuitry

CPC1966 AC Power Switch is ideal for saving energy in power systems for Industrial ,IT,
Consumer and Medical Products

Beverly, MA, - Clare, Inc., a subsidiary of IXYS Corporation (NASDAQ: IXYS), today announced the availability of the CPC1966, 3Arms AC Power Relay. The CPC1966 is an AC solid state switch utilizing dual optically isolated power SCRs as an integrated alternative to discrete optocoupler and Triac circuits. The device provides a blocking voltage capability of 600VP. In addition, zero-cross circuitry ensures AC load switching while minimizing the generation of transients.

Optically coupled circuitry provides exceptional noise immunity and 3750Vrms of isolation between the control and the output. Additionally, the 30Amp surge rating enables the CPC1966 to handle a variety of resistive and reactive loads. As a result, the robust CPC1966 is well suited for industrial environments where electromagnetic interference would disrupt the operation of plant facility communications and control systems.

"This product is suitable for the growing needs to improve power efficiency in power supplies and other off line applications, especially when systems are idling or not delivering power to the load. The lost power in idle mode is frequently called 'vampire power lost'. Thus to reduce this power loss, the CPC1966 can cut off the input power by any controller, like a Microcontroller and thus save energy", commented Dr. Nathan Zommer CEO of IXYS Corporation. "This is an extension of the IXYS integrated power management solutions to save energy". Maximum input control current to the input infrared LED for switching is 5mA.

Applications include: Motor control, valve and solenoid control, robotics, IT and
server power supplies, medical equipment, railroad and traffic controls, consumer
electronics, industrial controls, and, test and measurement equipment. The CPC1966, available in the Power SIP package, is certified to the UL 508 Standard for industrial control equipment.

Pricing and Availability

The CPC1966 AC Power Relays are available in production quantities. Pricing for OEM quantities of 10KU is $2.50.
