Product Overview: The DS11 Series Conversion Unit is a DC motor drive manufactured by Ryosan Denki for controlling DC motor speed and operation. It uses SCR-based power conversion to regulate motor voltage and current based on analog speed reference inputs, typically from a potentiometer. The drive features current feedback circuitry with sense resistors (DSR) and optional external isolator compatibility. Common applications include paper processing machinery and other industrial equipment requiring precise DC motor speed control. Key internal components include power SCRs, electrolytic capacitors, current sensing resistors, and analog control circuitry for voltage and current feedback regulation.
Category: Motor Controls
Manufacturer: Ryosan Denki
Manufacturer Part Number: D36X00256
Also Known As(AKA): DS200208G03
Common Failures
The DS-11 DC drive may experience issues related to its speed adjustment functionality. Common symptoms include the drive not responding to the speed adjustment potentiometer. This issue can be traced to components on the control board, particularly current sense resistors and various capacitors, which may become defective over time.
Repair Approach
We evaluate each unit individually. Repairs may involve replacing defective components such as resistors and capacitors on the control board. During evaluation, the continuity of feedback resistors and the condition of diodes are also examined. If necessary, capacitors on the control board are replaced to restore functionality.
Testing & Quality
After repairs, each unit undergoes testing including a burn-in test with a motor to ensure proper operation under load. Quality checks are performed by our technicians to confirm the reliability of repairs.
