The CPC1966B is an optically, isolated AC power switch that utilizes dual power SCR outputs. It includes zero-cross turn-in circuitry to minimize the generation of transients, and has a blocking voltage of 800 V.
The new 8-pin Power SOIC package provides 5000 V (rms) of isolation between the input control and the output while optically coupled circuitry provides exceptional noise immunity. Additionally, the 30Amp surge rating enables the CPC1966B to handle a variety of resistive and reactive loads. As a result, the robust CPC1966B is well suited for industrial environments where electromagnetic interference would disrupt the operation of plant facility communications and control systems.
Input control current to the infrared LED for switching is 5mA. Applications include: Motor controls, AC power control, valve and solenoid controls, security door and gate latches, lighting, AC power generation and distribution, home automation and HVAC controls. “This product expands the power range of our SSR’s, and with our Zilog MCU’s, provides a total system solution for digital power and load management, that is desirable for our customers to save energy and automate their equipment. Thus it’s ideal for robotics, IT and server power supplies, medical equipment, railroad and traffic controls, consumer electronics, fitness equipment, industrial controls, and, test and measurement equipment”, commented Dr. Nathan Zommer CEO of IXYS.
The CPC1966B, available in the 8-pin Power SOIC package, is pending certification to the UL 508 Standard for industrial control equipment.
