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
