ABB AGPS-21C Power Supply Module

• Output Specifications: Delivers a stable +24 V DC output with a maximum current of 10 A and continuous power output of 240 W.
• Redundancy Support: Can be paired with another AGPS-21C module to form a redundant power system, enabling automatic failover during single-power faults.
• Hot-Swappable Design: Allows safe module replacement during system operation, minimizing maintenance downtime.
• Status Monitoring: Equipped with LED indicators for real-time display of “Power Normal,” “Redundancy Status,” and “Fault” signals. Diagnostic data is also uploaded to the control system via the backplane bus.
• Protection Mechanisms: Built-in overvoltage, overcurrent, short-circuit, and overheating protection ensure safe shutdown under abnormal conditions, safeguarding downstream equipment.

Functional Characteristics

• High Efficiency: Optimized power conversion reduces energy waste and heat generation.
• Wide Temperature Adaptability: Operates reliably in temperatures ranging from -40°C to +85°C, suitable for harsh industrial settings.
• Compact Design: Space-saving form factor facilitates installation in confined control cabinets.
• Global Certifications: Complies with international safety and environmental standards, including CE and RoHS.

Application Scenarios

• Power Supply for FTE Network Switches: Provides redundant power to Fault Tolerant Ethernet (FTE) network switches in ABB Experion PKS systems, ensuring uninterrupted network communication.
• Main Power Unit for Remote I/O Cabinets: Serves as the primary power source for remote I/O stations, such as PM I/O units, in distributed control systems.
• Critical Communication Equipment: Powers key communication devices in control rooms or field junction boxes, maintaining connectivity during power fluctuations.
• Safety Instrumented Systems (SIS): Acts as an auxiliary power unit for SIS applications requiring high availability and reliability.

Additional Features

• Seamless Integration: Works natively with ABB Experion PKS architecture, supporting remote diagnostics and predictive maintenance.
• Automatic Load Balancing: Achieves balanced power distribution without external configuration when used in redundant setups.
• Fault Tolerance: Redundant design meets industrial high-availability standards, preventing network interruptions or control failures due to single-point power faults.
