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. A version (/S) of these controllers also incorporate an OFF switch when the potentiometer is fully anti-clockwise.
The controller has an integral RC Snubber network for control of inductive loads.
Minimum Set Speed adjuster (at the rear) allows the designer/installer to fix a minimum output voltage level to prevent a motor being driven too slow.

Infinitely variable 0-98% output
Optional OFF switch on potentiometer (/S versions)
Minimum Set Speed Adjuster
Single hole fixing
Rugged and compact
Large triac for inrush protection
Integral RC Snubber
Suitable applications for most single-phase mains voltage driven Motors & Fans
