Description

The UAA2022 is a Zero Voltage Switch Power Controller designed to drive triacs with the Zero Voltage technique. It allows RFI-free power regulation of resistive loads and is commonly used in the precision regulation of electrical heating systems such as panel heaters or irons. With its built-in digital sawtooth waveform, it enables proportional temperature regulation action over a ±1°C band around the set point. The UAA2022 also offers programmable temperature reduction for energy savings, sensor failsafe for security, and adjustable hysteresis for applications that require high hysteresis. It features a low external component count and is available in Pb-Free packages.
