400 V motor 1,5 A | Remote 5-step fan speed control

This transformer controller has an analogue input ranging from 0 to 10 V. It controls three-phase 400 volt motors. The maximum motor current (combined) is 1,5 A. The motor voltage is reduced in five steps to manage the speed using autotransformer technology. An analogue control signal (0-10 V) or an external potentiometer is used to pick one of these five levels. A precise sinusoidal output voltage ensures silent motor running. If the TK monitoring feature detects overheating, it shuts the motor. Surface mounting is possible with the IP54 enclosure. The power source voltage is 400 VAC.

With this 10 KOhm potentiometer you can directly control EC fans. If you want to control the speed of an AC motor, connect this potentiometer to an Electronic Fan Speed Controller (EVS, MVS) or frequency converter (FI-E). This potentiometer has an adjustable resistance of 0-10 kΩ. The device does not require a specific power supply, but the input signal must be between 0 and 12 VDC. Most EC fans, electronic speed controllers or frequency converters have an output with the required voltage. Depending on the position of the dial, the feedback voltage varies, regulating the Fan Speed. The dry contact output can be used to remotely give a start-stop command to the fan or other equipment. The splash-proof housing allows recessed installation (IP44) or surface mounting (IP54).
