Product Description

24v pwm brush dc motor controller 24V 200W dc motor speed controller for welding machine 

                           

                                LK4Q02
 

Product performance

 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.

 

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: 0-5V 0-10V or controlled by potentiometer

A broader scope of input voltage:20-55V
