Speed controllers are used in ventilation systems to regulate the speed of the fan motor rotation.
Speed and operation control of the device is done with a special knob on the face panel.
Minimum rotation speed is defined by a pot resistor.
Several fans can be connected to one and the same speed controller, provided that their total power and operating current do not exceed the rated speed controller parameters.
Speed controllers can be mounted either onto the walls (RS-N model) or into standard electrical junction boxes (RS-V model).
Equipped with an RFI filter and an overheat protector (safety fuse) with current intensity of 2,5 A (a spare overheat protector is included into the kit).
Speed controllers are designed for energy saving purposes. They also help reduce the fan’s noise level by setting the low rotation speed when there is no need for the fan to operate at maximum, prolonging the service lifetime of the device.
