F/R 12V 100W 150W DC Motor PWM Speed Control

I. Product characteristics:
This series of speed controller is a low voltage DC four-quadrant regeneration pulse width controller adopts special single-chip intelligent control system and has rapid response speed, steady operation, reliable work status and multiple protection functions.
1. SMT technology, small size
2. Pulse width modulation 
    Low noise during operation, high efficiency, and low maintenance cost which better enhance the service life of DC motor.
4. Four-quadrant regenerative operating mode5. 
5. Regenerative braking function
6. It doesn't need external reversing contactor and will not result in electric motor parts or other components overheating or burning down.
7. Enable/ reversing terminal
To realize certain functions by using simple passive switching value or transistor collector open circuit.
8. Status indicator light
 Power supply indicator and over-current alarm indicator can provide the visible status of speed controller.
9. Output current setting function (amplitude limiting)
10. Torque compensate function
