1 U.

5-stage fan speed controller with integrated calendar function. It controls single-phase motors. The (combined) maximum current is 10 A. The speed of the AC fan is regulated by reducing the motor voltage using autotransformer technology. This technology produces a perfect sinusoidal motor voltage and ensures quiet motor operation. Two optimum motor speeds selectable. Day-week programmed timer allows switching. TK monitoring function stops the motor in case of overheating. Motor restarts automatically after power failure. The enclosure can be surface mounted indoors (IP54).
