400 V motor 8 A | temperature control

This fan speed controller is specifically designed for controlling three-phase 400 V motors. The maximum combined current of 8 A. The calendar function allows setting 2 optimal motor speeds, and the timer with a day-week configuration enables automatic switching between these speeds based on predefined schedules. To ensure motor safety, the controller includes a TK monitoring function that monitors motor temperature. If overheating is detected, the controller will deactivate the motor to prevent damage. In the event of a power failure, the controller is equipped with an automatic restart feature., i.e. once the power is restored, the motor will automatically restart without the need for manual intervention. The enclosure of the controller is suitable for surface mounting indoors and has an IP54 rating, providing protection against dust and offering resistance to water splashes. The AC fan speed control is achieved by reducing the motor voltage using autotransformer technology. This technology generates a motor voltage with a perfect sinusoidal waveform, ensuring smooth and quiet motor operation. The supply voltage for the controller is 400 VAC.

This mechanical thermostat controls temperatures between 0 and 40 °C. The output contact can switch loads up to 16 A. The requested temperature can be adjusted via the rotary knob. The ambient temperature is measured via the spiral sensor. This thermostat can be used for heating or cooling ventilation applications in warehouses, greenhouses, stables, etc. The enclosure can be wall-mounted. It offers an IP54 protection against ingress of dust and moisture. This thermostat does not require a supply voltage.
