Replacement circuit for ST2R1 series

The ST2R1 series are fan speed controllers with a built-in day-week timer. They can switch between two optimal motor speeds (high-low control). The TK monitoring function switches off the motor in case of overheating. This electronic board provides the power supply for the day-week timer and the TK monitoring function of the ST2R1 series transformer fan speed controllers up to 7.5 A.
