Review on LEDMOMO 1203BB Controller: ποΈ Adjustable and Reversible Control Powerhouse by John Brouillard
Works great to give me control of the exhaust fan speed in my bathroom on wheels.
The correct way to control the speed of small DC motors is PWM. This allows speed control at maximum torque, which is not possible when using a rheostat instead. This one is pretty cheap and works well although I haven't used it much yet.
- Note! The DC motor speed controller is connected to a DC power supply. Never connect the device directly to a 220 V AC household socket.
- Expensive
