10A Variable & Switched ac Regulator with RFI Suppression, QVR/RFI and QLC/RFI

QVR/RFI: Variable min to max operation,QLC/RFI: Switched variable potentiometer

Compact, robust, phase angle power regulators with integral RFI filter networks for controlling single phase mains driven loads
Suitable for quartz lamps, transformers or conventional resistive heating elements in single, series or parallel configuration

25A High Power, PSR-25 and TPSR-25 with Thermistor option

Full wave ac phase-angle controller capable of regulating loads up to 6 kW (25 A) at 230 Vac. The controller provides a variable phase-controlled output to the load dependent on the value of the potentiometer wired across connections 3 & 4. The thermistor option allows proportional control of blower speed in response to temperature. It is suitable for the regulation of fan speeds in heating, ventilation and air-conditioning systems.

Note

Select for use a plastic housed potentiometer with a plastic shaft.

Low thermal impedance and high isolation
Operates down to 100mA load current
Internal snubber
