Features: Circuit optimization design, stable performance, suitable for long-term work. The maximum output current is 15A, and the motor lines ABC are not in order.This motor speed controller is mainly used for DC motor speed adjustment. The input voltage should be equal to the rated voltage of the motor within 5-36V, and 220V cannot be input.Three-phase brushless (BLDC) for DC motor speed uses high-quality chips to achieve wide voltage, smooth operation without noise and vibration.You can use it on a brushless motor with a speed range of 0-(rpm). Knob specification 100K, with switch.Easy to use, stable performance and simple operation.Specifications: Material: ABS + Electronic ComponentsInput Voltage: Dc5-36v (the Specific Voltage is Equal to the Rated Voltage of the Motor)Output Current: within 15afor Protection Current: 15aForward and Reverse: BidirectionalSpeed Regulation Mode: Potentiometer (270 Degree Linear)Speed Range: 0100%Supported Motor: Brushless MotorWiring Type: Barrier Terminal BlockKnob Specification: 100k (with Switch)Size: As PicturedPackage Includes: 1x Motor Speed Controllernote: Please allow 1-2cm errors due to manual measurement, make sure that you do not mind before you order.
