AC motor 7,5 A | Remote 5-speed control

This transformer controller has an analogue 0-10 V input. It controls single-phase motors. The (combined) maximum motor current is 7,5 A. The speed is regulated in 5 steps by reducing the motor voltage via autotransformer technology. These 5 levels are selected via an analogue control signal (0-10 V) or via an external potentiometer. The output voltage with a perfect sinusoidal shape guarantees quiet motor operation. The TK monitoring function disables the motor in case of overheating. The IP54 enclosure can be surface mounted. The supply voltage is 230 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).
