UAA2016: Zero Voltage Switch Power Controller
For complete documentation, see the data sheet
Product Description
The UAA2016 is designed to drive triacs with the Zero Voltage technique which allows RFI-free power regulation of resistive loads.
Operating directly on the AC power line, its main application is the precision regulation of electrical heating systems such as panel
heaters or irons.
A built-in digital sawtooth waveform permits proportional temperature regulation action over a +/-1°C band around the set point. For
energy savings there is a programmable temperature reduction function, and for security a sensor failsafe inhibits output pulses
when the sensor connection is broken. Preset temperature (i.e. defrost) application is also possible. In applications where high
hysteresis is needed, its value can be adjusted up to 5°C around the set point. All these features are implemented with a very low
external component count.
