Electronic Speed Controller offers stepless speed control, an economic method widely used for controlling commercial & industrial fans.
These controllers are unique in that hard and soft starting are built into one controller. This means an extractor fan can start at full speed and run for a short period of time. This is a significant advantage with fans used for kitchen extract or higher pressure systems were a surge can kick start air movement.
ON/OFF switch on the side of the controller lights up to indicate power is at the controller. Variable speed control is pre-set minimum to full speed and anywhere in-between.
In addition, the controller is protected to IP54 making it suitable for mounting in kitchens or where high humidity is present.
