AC fan speed controller 400 VAC with overload protection - 6 A


This is a transformer fan speed controller with thermomagnetic circuit breaker. It controls three-phase voltage controllable motors with a maximum current of 6 A. The fan speed is regulated in 5 steps by varying the motor voltage. The digital input can be used for remote start-stop commands. After a power failure, the motor will automatically restart. In case of a short circuit or overload, the thermomagnetic circuit breaker will immediately trip and deactivate the motor. The output voltage with perfect sinusoidal shape, guarantees quiet motor operation. The metal enclosure allows surface mounting in indoor environments (IP54). Available voltage taps: 0-130-180-230-300-400 VAC.

Solution code
Title
Description
Manual fan speed control - AC voltage controllable motor
This solution controls three-phase 400 V motors. The maximum motor current is 6 A. Typically, it regulates fan speed in HVAC applications. The fan speed can be selected via the 5-step rotary switch. In OFF position (zero), the motor is disabled. The digital input can be used for remote start-stop commands. The thermomagnetic circuit breaker provides protection against overload. After a power failure, the motor automatically restarts. The autotransformer technology generates a motor voltage with a perfect sinusoidal shape. This guarantees quiet motor operation.
