Review on Greartisan 6V-90V 15A PLC DC Motor Speed Controller PWM Variable Speed Regulator Governor Switch CCMHCN With Speed Control Knob by Byron Howell

Worked great on the Fantastic Fan for speed control and to reduce amp draw compared to the original three speed resistor. Wired it up so a push button toggle switch cuts power to the circuit, and the original forward/reverse switch still controls direction. No audible noise from controller, and a nice drop in amp draw. Circuit board was a little big for the space, but mounted it at an angle and shaved a little material off the heat sink to make it work.
