DDS-100 series DC motor speed regulatorDetailed product description：

The DDS-100 series DC motor speed controller is widely used in industries such as machine tools, paper printing, textile printing and dyeing, optical cable equipment, packaging machinery, electrical machinery, food processing machinery, rubber machinery, biological equipment, printed circuit board equipment, experimental equipment, welding and cutting, light industry machinery, logistics and transportation equipment, locomotives and vehicles, medical equipment, communication equipment, etc.

Performance of DDS-100 series DC motor speed controller:
1. Has relatively hard mechanical properties, with a static error rate of 1%. 2. Has a wide speed range, (0-maximum)
3. It has a fast dynamic response process. 4. It has an automatic smooth transition process for acceleration and deceleration time
5. Better excavator characteristics, able to automatically limit overload current to the set value current
6. High reliability, compact structure, and extremely high cost-effectiveness

Characteristics of DDS-100 series DC motor speed controller:
1. PWM pulse width modulation technology, low noise. 2. Speed ratio 1:100 (open-loop)
3. Double closed-loop PI regulation 4. High low-speed starting torque
5. Current setting, current limiting protection, overcurrent alarm function 6. Soft start/soft stop time setting function
7. Locking control function 8. Good followability and fast response speed
9. Standard signal interface (can be used for analog control of 0-5V, 0-10V, or 4-20mA with additional signal isolators)
10. Short circuit protection function
