Motor control with day-week timer
ST2R1 series are transformer fan speed controllers with day-week timer. They can switch between two optimal motor speeds. They control single phase voltage controllable motors with a maximum current of 13 A. The fan speed is regulated in steps by varying the motor voltage. The TK monitoring function protects the motor against overheating. After a power failure, the motor will automatically restart. The enclosure allows surface mounting in indoor environments (IP54).
