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.

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

Note

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