12V-40V 10A DC Motor Speed Controller PWM Stepless Speed Switch

1. Input voltage: DC12V-40V
2. Control power: 0.01-400W
3. PWM frequency: 13khz
4. PWM pulse width speed range: 10-100 percent
5. Applicable current: rated current 8A, through the current up to 10A, static current 0.02A (standby state)
6. Weight: without stand about 62.6 g, with stand about 68.6 g
7. Size: about 7 x 6.5 cm

Features:
1. 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 function
2. The circuit board is made of military-grade boards with meticulous workmanship and reliable quality, which is widely used in industrial production
3. 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 300V20A

Precautions 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 out
2. DC power supply positive and negative poles can not be reversed, otherwise the governor will be damaged
3. 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 sequence
4. Adjusting the potentiometer knob can change the output duty cycle of the governor, thus changing the speed of the motor
