Using this controller to control the speed of DC motor, high efficiency, high torque, low heat generation, with reverse polarity protection and high current protection function2. The circuit board is made of military-grade boards with meticulous workmanship and reliable quality, which is widely used in industrial production3. Power tube using IRF3205 the bull, do not worry about not moving your motor. (parameters leakage current Id large value: 82A; voltage Vds large: 75V; open-state resistance, Rds (on): 0.013ohm)4. Terminal use 8500 high current terminal, labeled 300V20APrecautions and instructions for use:1. DC motor governor input is DC, not directly connected to AC power (such as: household 220V AC), otherwise it will be burned out2. DC power supply positive and negative poles can not be reversed, otherwise the governor will be damaged3. The motor can not be divided into positive and negative, when the running direction is inconsistent with the expectation, you can change the direction by adjusting the wire sequence4. Adjusting the potentiometer knob can change the output duty cycle of the governor, thus changing the speed of the motorSpecification: Package Weight One Package Weight 0.07kgs / 0.16lb One Package Size 10cm * 8cm * 3cm / 3.94inch * 3.15inch * 1.18inch Qty per Carton 180 Carton Weight 13.70kgs / 30.20lb Carton Size 50cm * 32cm * 32cm / 19.69inch * 12.6inch * 12.6inch Loading Container 20GP: 520 cartons * 180 pcs = 93600 pcs 40HQ: 1209 cartons * 180 pcs = 217620 pcs
