FEATURES
• Variable 0-98% output.
• Minimum set speed adjuster.
• Single-hole fixing.
• Rugged and compact.
• Large triac for inrush protection.
• Integral R-C snubber.
DESCRIPTION
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 and pumps. They give fully adjustable voltage outputs from
zero to maximum.
The controller has an integrated RC 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).
APPLICATION
Suitable for most simple mains driven motors and fans.

NOTE 2:
Minimum set speed adjustment is accessed via a rear
cover hole (this is covered by an adhesive label).
Adjust the cermet screw using a small terminal
screwdriver .
NOTE 1:
The unit must be fastened to a heatsink (suitable panel)
rated at 2ºC/W or better for a 15A operation.
Heatsink paste is essential for use between surfaces (of
unit and heatsink) for good thermal bonding.
