Feature: 1. Convenient speed control, the speed is controlled by the connected potentiometer and the adjustment switch. 2. High-end configuration, our motor controller uses the PWM modulation system to regulate light and speed. 3. In addition, it is also designed with a radiator for heat dissipation generated by the MOS tube. 4. The motor drive controller can be applied to DC brush motor speed regulation, automotive motor speed adjustment, production line conveyor belt speed control, electronic fan speed control, etc. 5. DC 10V-50V wide operating voltage. Specification: Item Type: DC Motor Speed Controller Working Voltage: DC10V-DC50V, wide working voltage range Control Power: 0.01-3000W (maximum instant start current 60A, long-term working current should be controlled within 30A) Different working voltages correspond to different control powers as follows; Working Voltage 12V, 12Vx60A = 720W Working Voltage 24V, 24Vx60A =1440W Working Voltage 36V, 36Vx60A =2160W Working Voltage 40V, 40Vx60A =2400W Working Voltage 50V, 50Vx60A =3000W Quiescent Current: 0.04A (When the working voltage is between DC10V and DC50V, the static current will not exceed 40mA) PWM Duty Cycle: 5% -100% PWM Frequency: 15khz Working Temperature: -20~40℃ (This motor speed controller is of industrial grade quality and can work stably in environments below 0℃.
