UAA2016
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.
