This is a PWM driver for speed control of smaller DC motors up to 450W or 10A continuous (1200W 15A peak)
Be sure to take cooling into account at high currents, ensure there is adequate ventilation.
Barrier screw terminals for connecting your supply and motor.
Of course you could use this for other things that you want to PWM control, like heating resistors, leds, umm… probably other things I can’t think of.
PWM frequency is 25Hz
Note that simple PWM drivers like this do not compensate for motor load if it chanegs, if you have a variable load applied to your motor then this may not work that well for you unless you are adjusting the knob to match the load as it changes like a throttle. Simple speed controllers like this are best suited to relatively constant load situations, like fans, circulating pumps, simple constant rotation like in window displays, turntables, that kind of thing.
