Fan speed control - TK monitoring - STRS1-50L22 TK

This is a transformer fan speed controller. It controls the speed of single-phase voltage controllable motors with a maximum current of 5 A. The AC fan speed is regulated in 5 steps by varying the motor voltage. The output voltage with perfect sinusoidal shape, guarantees quiet motor operation. The TK monitoring function protects the motor in case of overheating. The enclosure allows surface mounting in indoor environments (IP54). Available voltage taps: 0 – (80) – 110 - 140 – 170 – 190 – 230 VAC.
