Wide voltage PWM DC governor Description: 1) Operating voltage: DC12V-DC52V 2) Control current: the maximum operating current of 10A, with overcurrent and short circuit protection, short circuit time is not more than 30 seconds. 3) to control power: voltage * current = power (12V when the power is 12 * 10 = 120W .......... 52V when the maximum power of 300W) (customers the choice of governor recommended with sufficient margin, for example, the motor is 100W recommend choosing 200W governor.) 4) Dimensions: length 72mm x 56mm, without potentiometers protruding parts 5) Frequency: 18KHZ 6) Note: Please correct the wiring diagram of wiring on the picture, the input voltage polarity can not be reversed, and reversed the damage, as well as man-made damage not covered under warranty. (But can provide paid services) Package List: 1 * DC12V-56V DC Motor Driver
