About Brushless DC Motor Speed Controller, DROK DC 6-50V
DROK BLDC Motor Controller Parameters: Operation voltage range: 6-50V Rated current: 16A Max output current: 20A Max power: 380W Over-current protective function: Yes The highest rotating speed: 10000~15000 revolutions Dimension: 63x45x30mm Wiring Ports: 1. MA MB MC: phrase line output connects to the motor 2. 5V GND: mainboard built-in power supply (the current cannot be exceeded 30MA) 3. VCC GND: the motor power supply (connect to external DC power supply) 4. SC: output pulse signal of rotating speed 5. Forward and reverse control: forward and reverse rotation control (or can be connected to the external switch) 6. VR: speed control signal input (with an onboard potentiometer for speed regulation, can also be connected to external 0-5V analog simulation, PWM duty cycle, support dual signal input speed regulation) Notes: 1. We recommend adding the fuses, as without fuses on the power supply circuit of the motherboard. The reversed connection will cause some of the chip permanent damage. 2. In the normal operation, the motor output has the over-current protection. Please do not artificially short-circuit, because the module power current is large. Once short-circuit, has the possibility of burning line tube. Please use low current low-voltage testing in the first wiring test; then connect the larger current and voltage. Due to the bare board module sold, please attention wiring thread insulation and prohibited strong voltage touch onboard parts. 3. Do not connect the drive motor which has obviously inconsistent voltage, current, power, to avoid the unreasonable damage. Package Includes: 1 x DC Brushless Motor Driver Board
