ABB SAFT110POW Power Supply – Obsolete SAFT 110 Spare Part

RFQ support for obsolete parts: Send the model number, required quantity and destination so DriveKNMS can confirm sourcing options before quotation.

Technical Specifications

Note: Electrical parameters (input voltage range, output ratings, protection class) vary by revision. Confirmed specifications are provided upon request based on the specific unit serial number. No parameters are published here that cannot be verified — accuracy on obsolete hardware is a safety matter, not a formality.

Solving the Discontinued Hardware Crisis

The ABB SAFT 110 drive platform was widely deployed across pulp and paper mills, steel processing lines, marine propulsion systems, and heavy industrial applications throughout the 1980s and 1990s. Its power supply module — the SAFT110POW — is the electrical backbone of the entire drive assembly. Without it, the drive does not operate.

The core problem facing maintenance engineers today is not technical complexity — it is availability. ABB's official end-of-life declaration means that replacement units cannot be sourced through standard distribution. The installed base, however, remains substantial. Thousands of SAFT 110 drives continue to run production-critical equipment in facilities that have neither the budget nor the operational window to execute a full drive replacement program.

Condition & Reliability Assurance

DriveKNMS applies a structured 5-step quality process to all obsolete power supply modules before dispatch review:

• Step 1 – Visual and Mechanical Inspection: Full board inspection for physical damage, pin corrosion, solder joint integrity, and connector condition. Units with compromised connectors or cracked PCB traces are rejected at this stage.
• Step 2 – Electrolytic Capacitor Assessment: Capacitor aging is the primary failure mechanism in power supply modules of this era. Each unit undergoes ESR (Equivalent Series Resistance) measurement. Units with capacitors outside acceptable tolerance are either recapped with equivalent-spec components or removed from inventory.
• Step 3 – Firmware and Revision Verification: Where applicable, firmware version and hardware revision are documented and matched to the customer's existing system revision to confirm compatibility before dispatch review.
• Step 4 – Functional Power-On Test: Units are bench-tested under controlled conditions to verify basic power delivery function prior to packaging.
• Step 5 – Anti-Static Packaging and Documentation: All units are shipped in ESD-safe packaging with a condition report. Serial number and test date are recorded for traceability.

Key Features for System Maintenance

Should I buy more than one unit?
For facilities operating a single SAFT 110 drive, one spare is the minimum defensible position. For multi-drive installations, the standard recommendation is one spare per two to three drives, held on-site. Given that global availability of the SAFT110POW continues to decline, procurement decisions made today will be more cost-effective than those made after a failure event.
