United Automation Fan Speed Controller, 230 V ac, 15A Max, Infinitely Variable

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
