Overview
The UAA2016P, produced by onsemi, is a Zero Voltage Switch Power Controller designed to drive triacs using the Zero Voltage technique. This method allows for RFI-free power regulation of resistive loads. The device operates directly on the AC power line and is primarily used for the precision regulation of electrical heating systems, such as panel heaters and irons. It features a built-in digital sawtooth waveform that enables proportional temperature regulation over a ±1°C band around the set point, ensuring precise and stable temperature control.
