SpeedControl 3×100 – 3 phase triac controller for ventilator motors up to 4kW.
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 robust metal casing for protection under difficult conditions. The unit can be mounted in electric switch boards or standard enclosures.
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.
Control signal options: Potentiometer 10K, 0-10V normal and inverted, electronic start/stop. 15V DC output for control modules. The control unit is galvanic isolated from net. It is possible to adjust the minimum and maximum voltage output and soft start time.
