AC fan speed control - TK monitoring

STRS4 series are transformer fan speed controllers with TK monitoring. This function deactivates the motor in case of overheating. They control three-phase voltage controllable motors with a maximum current of 14 A. The AC fan speed is regulated by varying the motor voltage in steps. The perfect sinusoidal shape of the motor voltage guarantees a quiet motor operation. The fan speed is selected via the 5-step rotary switch. This switch also has an OFF position. The enclosure allows surface mounting in indoor environments (IP54).
