SpeedControl 3x60 E with build-in potentiometer - 3 phase voltage controller for ventilator motors up to 2,2 kW.

This regulator is most suitable as spare part for older ventilation plants using voltage control. Plants using newer energy efficient motors are most likely not suitable for voltage control as the motors will be having an extreme power consumption and overheat. This kind of efficient motors must be regulated by a frequency converter. We will be pleased to guide you to the right frequency converter.

The unit is mounted in a box. It is possible to adjust the minimum and maximum voltage output and soft start time.

The controller uses an internal floating neutral to avoid reverse current. Without neutral the motor voltage can be reduced to 50% which is a normal control range for ventilators and pumps. On request the controller can be supplied with N connected allowing the output voltage to be reduced to approx. 80V.
