AC fan speed control

STR-4 series are transformer fan speed controllers. They control three-phase voltage controllable motors with a maximum current of 14 A. The AC fan speed is regulated in steps by varying the motor voltage. The output voltage with perfect sinusoidal shape, guarantees a quiet motor operation. The fan speed is controlled in 5 steps via the rotary switch. This switch also has an OFF position. The enclosure allows surface mounting in indoor environments (IP54).
