ABB SAFT112POW – Compact 24 VDC Power Module for Advant/SattCon Control Racks

The ABB SAFT112POW is a rack-mounted power supply module designed to feed the internal backplane of ABB control systems in the Advant/SattCon family. From my experience, it’s the kind of “keep one on the shelf” spare that keeps legacy DCS/PLC racks healthy, especially where uptime matters. You might notice that plants typically pair it with a second unit for redundancy; when one supply is offline, the other keeps the controller and I/O stable.

Key Features

• 24 VDC cabinet supply – Typically operates from a 24 VDC nominal feed (SELV/PELV), ideal for standard control panels.
• Backplane power stabilization – Provides regulated rails to the rack so CPUs and I/O cards get a clean, stable source.
• Designed for redundancy – In many cases, two supplies can run in parallel; one thing I appreciate is how that reduces unplanned downtime.
• Integrated protection – Overload and short-circuit protection help safeguard the controller base and downstream modules.
• Status indication – Front LEDs (typical) provide quick health checks for maintenance teams during rounds.
• Serviceable form factor – Backplane-mounted module fits existing ABB racks; swap time is usually minutes with proper procedures.
• Industrial temperature range – Built for cabinet environments commonly specified up to +55 °C.
• No process I/O – Pure power distribution to the internal bus; no field signal wiring to manage.

Related or Supporting Products

• ABB SAFT190POW – Higher-capacity power module in the same family; typically used where the rack load is heavier or for redundancy pairs.
• ABB CP-E 24 VDC DIN-rail power supplies – External 24 VDC sources (various current ratings) to feed the SAFT112POW input, useful when cabinet power needs an upgrade.
• Rack carriers and terminal bases (Advant/SattCon) – Matching backplanes and carriers ensure proper mechanical fit and stable contact to the internal bus.

A maintenance lead in a chemical plant mentioned they swapped a SAFT112POW in under 10 minutes during a planned stop, and the redundant setup kept the controller alive the entire time. That’s typically how these modules earn their keep.

Installation & Maintenance

• Cabinet and mounting – Install in the designated ABB rack/backplane. Keep 24 VDC wiring short and secure; use properly rated ferrules.
• Power feed – Supply SELV/PELV 24 VDC with adequate current headroom. In most cases, separate the power feed from noisy loads and provide proper grounding.
• Ventilation – Ensure free airflow in the enclosure; avoid placing heat-generating devices directly beneath the module.
• Wiring – Use industrial-grade cables (typically 0.5–2.5 mm²). Tighten terminals to manufacturer torque specs to prevent intermittent faults.
• Redundancy – For critical systems, configure dual power modules where supported. Verify load sharing and failover during commissioning.
• Safety – De-energize before single-supply replacement. If hot-swap is permitted in your system, follow ABB’s documented procedure and PPE requirements.
• Routine checks – Inspect terminals quarterly, clean dust with dry air, and review event/LED indicators. Firmware isn’t applicable; focus on electrical health and contact integrity.
