Description
SDCS-POW-1C: Product Overview
The ABB SDCS-POW-1C is a purpose-built power supply module designed for integration with ABB’s variable frequency drives (VFDs) and servo systems. Positioned as a critical power conversion component, it ensures stable DC power delivery to control boards, communication interfaces, and sensor networks within ABB’s ACS600/800/880 series drives. Its compact design and robust protection mechanisms make it indispensable for industries requiring uninterrupted motor control, such as metallurgy, water treatment, and material handling.
Role in Automation Systems:
As a primary power source for ABB drive control electronics, the SDCS-POW-1C handles:
-
Voltage Regulation: Converts 100–240V AC input to precise 24V DC output, minimizing voltage fluctuations that could destabilize drive control algorithms.
-
Load Distribution: Supplies power to critical subsystems, including:
-
Drive control boards (e.g., ACS880 CPU modules)
-
Fieldbus interfaces (e.g., PROFINET, EtherCAT)
-
Safety relays and diagnostic sensors
-
-
Fault Mitigation: Built-in protection circuits prevent damage from overcurrent, overvoltage, and thermal stress, ensuring compliance with IEC 61800-5-2 safety standards.
Platform Benefits (ABB SDCS Series):
-
Compatibility: Seamlessly integrates with ABB’s ACS600/800/880 drives, reducing system integration time.
-
Scalability: Supports parallel operation for redundant power configurations in high-demand applications.
-
Diagnostic Visibility: Status LEDs (power, fault) and Modbus-compatible registers enable real-time monitoring via ABB’s Control Builder software.

Core Features & Customer Value
1. Precision Voltage Regulation:
The SDCS-POW-1C employs a switching regulator topology to maintain ±2% output voltage stability, even under fluctuating input conditions. For example, in a steel mill’s rolling mill drive, this ensures consistent torque delivery to motors despite voltage sags caused by heavy machinery startups.
2. Compact Thermal Design:
Optimized heatsink geometry and natural convection cooling allow the module to dissipate heat efficiently without requiring active ventilation. In a water treatment plant’s pump control cabinet, this minimizes cooling infrastructure costs while ensuring reliability in high-ambient-temperature environments.
3. Fault-Tolerant Operation:
Integrated protection circuits isolate faults conditions (e.g., short circuits) to prevent cascading failures. In a chemical plant’s reactor agitation system, this safeguards the drive’s control board during transient faults events, reducing unplanned downtime.
4. Modular Integration:
Designed for DIN rail mounting, the module supports quick replacement and expansion. When paired with ABB’s SDCS-FEX communication modules, it enables distributed I/O architectures for scalable automation solutions.
