Product Description

The ABB SDCS-POW-1C is a dedicated electronic module designed to provide stable, regulated, and isolated DC power to the low-voltage control circuits within an ABB DC drive unit. It takes the unregulated voltage from the main drive’s auxiliary supply and converts it into the necessary clean power rails (e.g., $\pm 15\ \text{V}$, $5\ \text{V}$, $24\ \text{V}$) required by the various control boards, such as the SDCS-COM-81 and related I/O modules.

This module is fundamental to the drive’s operation as it ensures the immunity of the control electronics to voltage fluctuations and electrical noise often present in the power section of a large industrial drive.

Product Parameters

Product Advantages

• Control Stability: Provides highly regulated and filtered power, which is essential for the stable operation of the drive’s microprocessors and analog circuits.

• Noise Immunity: The high degree of isolation prevents electrical noise from the main power converter circuits from affecting the sensitive control electronics, ensuring reliable control execution.

• Protection Features: Often includes built-in protection against overcurrent and short circuits on the control power rails, protecting the expensive control modules (SDCS-COM-xx).

• Modular Design: Allows for easy replacement of the power supply unit without needing to replace the entire control assembly, simplifying maintenance and reducing repair time.

Important Precautions

• ESD Protection: As with all electronic control boards, the SDCS-POW-1C is sensitive to Electrostatic Discharge (ESD). Always handle the module using a grounded wrist strap.

• Input Voltage Check: Ensure the unregulated input voltage from the drive’s auxiliary supply is within the specified tolerance for the SDCS-POW-1C before applying power.

• Component Wear: Power supply boards contain components like capacitors that have a finite lifespan. Regular visual inspection for bulging or leaking components is recommended for preventive maintenance.

• Power Down: Always de-energize and lock out the main drive power and wait for the power capacitors to fully discharge before servicing or replacing this module.

Product Applications

The SDCS-POW-1C is a fundamental component in all industrial applications using ABB’s modular DC drive systems:

• High-Precision Control: Ensures stable operation in applications like rolling mills, paper machines, and extruders where continuous, accurate control is required.

• Motor Control Systems: Provides reliable power to the core logic that manages the speed, torque, and current regulation of the DC motor.

• Process Automation: Guarantees the stability of the control interface that links the drive to external PLC/DCS systems.
