ABB AGPS-11C – Compact Power Supply Module for Industrial Control Cabinets

The ABB AGPS-11C is a compact industrial power supply module designed to stabilize and distribute DC power inside automation cabinets. From my experience, it’s typically used to feed control electronics and I/O backplanes in ABB-based systems, where clean, reliable DC power is critical for uptime. You might notice that its footprint suits tight cabinets and retrofit jobs, which is helpful when you’re replacing like-for-like parts without reworking rack layouts.

Key Features

• Stabilized DC output for control electronics – Delivers clean power to control boards and I/O backplanes to reduce nuisance trips.
• Cabinet-friendly form factor – A plug-in module profile that typically fits ABB control racks, making field replacement straightforward.
• Protection and diagnostics – Overload/short-circuit protection and front status indication in many cases, so technicians can quickly verify health.
• Noise immunity – Designed for industrial environments with switching loads and VFDs; helps maintain stable voltage under electrical noise.
• Redundancy-ready architecture – Often used in dual-feed power architectures to maximize availability on critical lines.
• Serviceability – Tool-light access and predictable replacement routine; typically no firmware handling required.

Technical Specifications

Application Fields

The AGPS-11C fits maintenance and expansion tasks across process automation where ABB control platforms are deployed. Typical scenarios include:

• Powering I/O racks and controller backplanes in DCS/PLC cabinets
• Redundant DC feed setups for continuous process lines in chemicals, water, and power
• MRO spare for fast recovery after a cabinet power fault or aging supply failure
• Retrofit projects where form/fit compatibility reduces cabinet rework

A maintenance supervisor at a midstream facility told us the AGPS-11C “dropped into the existing rack and we were back online in under 30 minutes,” which seems to be a common theme with these compact ABB supplies.

Advantages & Value

• Reliability in harsh cabinets – Stable DC rails help avoid nuisance controller resets and intermittent I/O faults.
• Compatibility – Form factor and wiring approach are geared for ABB control cabinets, cutting engineering time during replacement.
• Lower downtime cost – Fast swap-over and clear status indication can shorten mean time to repair.
• Support – Application guidance and pre-shipment testing available to match your cabinet power design.

Installation & Maintenance

• Cabinet environment – Mount in a clean, dry control cabinet (IP54 or better recommended). Provide airflow paths; avoid placement near high-heat drives without baffles.
• Power wiring – Use correctly sized DC conductors and ring/fork terminals; verify protective earth continuity. In most cases, a 24 VDC UPS and surge protection improve availability.
• Redundancy – For A/B feed architectures, isolate returns and use OR-ing or redundancy modules as specified by your cabinet design.
• Safety – De-energize sources and lock out before removal or insertion. Check residual voltage on capacitors.
• Routine checks – Quarterly visual inspection for dust and loosened terminals; annual verification of output stability and ripple. Clean with dry air; avoid solvents.
• Lifecycle notes – Electrolytic capacitors age; many plants plan proactive replacement at 7–10 years depending on load and temperature.

Quality & Certifications

• CE compliant for industrial environments
• RoHS conformity for hazardous substances
• UL/CSA recognition for control equipment, where applicable
• Manufacturer-grade build and traceability; warranty: 365 days from shipment
