400 V motor 4 A | Remote fan speed control | display

This transformer controller has a 0-10V analog input. It controls a three-phase 400 volt motor. The (ombined) maximum motor current is 4 A. The speed is regulated in 5 steps by reducing the motor voltage via autotransformer technology. One of these 5 levels 1 is selected by means of an analog control signal (0-10 volts) or an external potentiometer. The full sine output voltage guarantees the quiet operation of the motor. The TK monitoring function deactivates the motor in case of overheating. The IP54 metal casing can be surface mounted. The supply voltage is 400 VAC.
