Electronic fan speed control

Infinitely variable fan speed control for AC voltage controllable motors. These electronic fan speed controllers allow you to regulate the rotational speed of AC fans manually or demand based. Phase angle control (triac technology) is used to adjust the motor voltage and to control the fan speed. Depending on the product serie, there is the choice between softstart or kickstart acceleration of the motor. Electronic (TRIAC) fan speed controllers are available for single phase 230 VAC or three phase 400 VAC voltage controllable motors.

Local fan speed control
Electronic (TRIAC) fan speed controllers with integrated potentiometer for continuous variable fan speed control of single phase AC voltage controllable motors. Via the integrated potentiometer, the correct fan speed can be selected manually. Some series also feature an integrated ON/OFF switch. Phase angle control (triac technology) is used to adjust the motor voltage and to control the fan speed.

Local fan speed control
Remote fan speed control
Electronic (TRIAC) fan speed controllers with an analogue input. An analogue signal is required as a reference for the requested fan speed. The motor voltage (and fan speed) will be controlled in function of the analogue input signal. These devices are designed for infinitely variable fan speed control of AC voltage controllable motors. There are different possibilities to generate the analogue input signal for the speed reference. Typical examples are: a potentiometer, a sensor, sensor controller, etc. This group features electronic (TRIAC) fan speed controllers for single phase 230 VAC or three phase 400 VAC voltage controllable motors. Phase angle control (triac technology) is used to adjust the motor voltage and to control the fan speed.

Demand controlled ventilation
Electronic (TRIAC) fan speed control based on the requested temperature, relative humidity, CO2 or differential pressure. Demand based fan speed control optimises the comfort of the inhabitants, while realising significant energy savings. The products in this group provide infinitely variable fan speed control for single phase 230 VAC voltage controllable motors in function of temperature, relative humidity, CO2 or differential pressure. Phase angle control (triac technology) is used to adjust the motor voltage and to control the fan speed.
