Zero Voltage Switch
Power Controller
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.
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.

... 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− ...

... For the 60 Hz case it is 34.13 sec. This is to comply with the European standard, namely that 2.0 kW loads cannot be connected or removed from the line more than once every 30 sec. The inertia of most heating systems combined with the UAA2016 will comply with the European Standard. 3. 350 mV corresponds to 5° ...

... Depending on the power in the load, choose the triac that has the lowest peak gate trigger current. This will limit the output current of the UAA2016 and thus its power consumption. Use Figure 4 to determine R the triac maximum gate current (I ) and the application GT low temperature limit ...
