12v DC Motor Speed Controller 30a 24v DC Motor Speed Control Circuit Reversible Speed Controller DC

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.

◆ SMT technology, small size

◆ Pulse width modulation

Low noise during operation, high efficiency, and low maintenance cost which better enhance the service life of DC motor.

◆ Four-quadrant regenerative operating mode

◆ 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.

◆ Enable/ reversing terminal

To realize certain functions by using simple passive switching value or transistor collector open circuit.

◆Status indicator light

 Power supply indicator and over-current alarm indicator can provide the visible status of speed controller.

◆ Output current setting function (amplitude limiting)

◆ Torque compensate function

◆ Double closed-loop PI regulation(current, voltage)

◆ Standard analog quantity signal control

   Analog quantity: 0-6V 0-10V or controlled by potentiometer

◆ A broader scope of input voltage:20-55V
