24V 48V brushed dc motor speed control 20A

I. Overview:
This brushed motor 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.

Ⅱ.Product Features
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.
3. Four-quadrant regenerative operating mode
4. Regenerative braking function
It doesn’t need external reversing contactor and will not result in electric motor parts or other components overheating or burning down.
4. Enable/ reversing terminal 
To realize certain functions by using simple passive switching value or transistor collector open circuit.
5. Status indicator light
 Power supply indicator and over-current alarm indicator can provide the visible status of speed controller.
6. Output current setting function (amplitude limiting)
7. Torque compensate function 
8. Double closed-loop PI regulation(current, voltage)
9. Standard analog quantity signal control 
   Analog quantity: 0-5V 0-10V or controlled by potentiometer 
10. A broader scope of input voltage: 20-55V
