Description

This variable thyristor speed controller can be used to regulate any 220 volt speed controllable fan motor up to a current rating of 1.8 amps. It can also be used to control a number of fans connected to the unit provided the total amperage of the fans does not exceed the rating of the controller.

The unit is manufactured in a high grade plastic and can be mounted either flush or surface.

The controller has an on / off switch and starts control of the fan at the minimum speed setting. By rotating the control knob in a clockwise direction, the fan rpm is increased gradually to maximum speed. The minimum starting speed can be adjusted  by means of a variable resistor located on the circuit board inside the unit.

For overload protection, the controller is equipped with a replaceable fuse.
