These variable phase angle regulators are robust, compact and enclosed units for 230V or 110V up to 15A single phase mains driven inductive loads, such as induction motors, fans & pumps. They give fully adjustable voltage outputs from zero to maximum. These controllers also incorporate an OFF switch when the potentiometer is fully anti-clockwise.
The controller has an integral R-C snubber network for control of inductive loads and a minimum set speed adjuster (at the rear) to allow the designer/installer to fix a minimum output voltage level to prevent a motor being driven too slowly.
The large triac enables the unit to handle high inrush currents with ample safety margin on industrial installations. An adhesive backed silver label and hairline knob are included for front panel mounting (or fitted to front of unit).
Suitable for most simple mains driven motors and fans
