Zero Voltage Switch
Power Controller
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.
