DDS-24/48 type DC motor speed regulatorDetailed product description：

The DDS-24/48 DC motor speed controller is a low-voltage DC four quadrant regenerative pulse width speed controller, which is intelligently controlled by a dedicated microcontroller. It has fast response speed, stable operation, reliable work, and complete protection functions.  
Adopting SMT technology and small size
Pulse width modulation
The motor has low operating noise, high efficiency, low maintenance, and better improves the service life of DC motors.  
Four quadrant regeneration operation mode
Regenerative braking function
No external reversing contactor is required, which will not cause overheating or burning of motor components or their assemblies
Enable/reverse terminal
One of the functions can be achieved through simple passive switching or transistor collector open circuit.  
status indicator light
The power indicator and overcurrent alarm indicator can provide visual status of the speed controller.  
Output current setting function (limiting)
Torque compensation function
Double loop PI regulation (current, voltage)
Standard analog signal control
Analog quantity: 0-6V 0-10V or potentiometer control can be used
Wide input voltage range: 20-55V
