Features This motor speed controller is mainly used for DC motor speed regulation. This motor speed controller supports CW and CCW rotation of DC motor. Stable performance, simple and most economical multifunction operation, ease of use, are compact brushless DC drives. This sensorless 3-phase brushless DC (BLDC) motor uses high quality chips for extended voltage. 100% brand new and high quality. Features: Input voltage: DC5-36V Front reversal: within 15A Input current: > Motor working current Speed control: potentiometer (linear to 270 degrees) Speed regulation range: 0-100% Support motor: brushless motor Connection Type: Barrier Terminal Button Specification: 100K (with switch) Module size: 10*6.8*4cm/3.93*2.67*1.57in Weight: 141 g Package includes: 1 x Motor Speed Controller Note: 1.
