3 phase voltage controller for ventilator motors. Suitable as spare part for older ventilation plants using voltage control. It is possible to adjust the minimum and maximum voltage output and soft start time.
NOTE: 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.
