Compatible Replacement & Equivalent Models
When the original PSU-0261-12A is unavailable or end-of-life, the following models may serve as functional equivalents. Compatibility must be verified against your specific system revision and firmware version.
- ABB 3KXG758003U0401 — Revised production variant; same electrical ratings, updated PCB revision
- ABB PSU-0261-12B — Next-generation replacement with enhanced thermal management
- ABB 3BSE013208R1 — Cross-platform power supply for AC800M series (verify pinout compatibility)
- Third-party equivalents — 12 V / 12 A DIN-rail PSU with matching connector footprint; consult Konmask technical team for validated alternatives
⚠ Important: Always confirm output voltage, current rating, connector type, and firmware compatibility before substituting any power supply module in a live control system.
Why Choose the Original Model
- System-validated performance: Designed and tested specifically for ABB control architectures — no compatibility guesswork
- Guaranteed electrical compatibility: Matched impedance, protection circuits, and bus signaling for ABB backplanes
- Warranty & support continuity: Using OEM parts preserves ABB system warranty and simplifies maintenance documentation
- Reduced commissioning risk: Drop-in replacement with no firmware or configuration changes required
- Long-term availability: Konmask maintains stock of legacy ABB modules to support extended plant lifecycles
Typical Applications
- ABB Advant / Master series DCS power distribution
- ABB AC800M / AC800F controller rack power supply
- Industrial process automation panels (oil & gas, chemical, power generation)
- Factory automation and machine control cabinets
- Redundant power supply configurations in critical infrastructure
- Spare parts inventory for plant maintenance and MRO programs
System Compatibility
| ABB System / Platform | Compatibility | Notes |
|---|---|---|
| ABB Advant OCS / Master | ✅ Confirmed | Primary target platform |
| ABB AC800M | ⚠ Verify | Check rack and backplane revision |
| ABB AC800F (Freelance) | ⚠ Verify | Confirm connector and voltage spec |
| ABB S800 I/O | ❌ Not applicable | S800 uses dedicated field PSU |
| Third-party DCS racks | ❌ Not recommended | Use generic DIN-rail PSU instead |
Selection Guide
Use the following decision flow to select the correct power supply module for your application:
- Identify your ABB system platform — Advant, AC800M, AC800F, or other
- Confirm rack/backplane revision — Check the system nameplate or engineering drawings
- Verify required output voltage & current — 12 V / 12 A for PSU-0261-12A; other ratings require different models
- Check redundancy requirements — Single PSU or N+1 redundant configuration?
- Confirm input power source — 24 V DC UPS-backed bus or 100–240 V AC mains
- Review firmware/hardware revision compatibility — Contact Konmask with your system serial number if unsure
- Place order or request a quote — Standard lead time: in-stock items ship within 1–3 business days

Replacement & Compatibility FAQ
Q: Can I use PSU-0261-12A as a direct drop-in replacement for 3KXG758003U0400?
A: Yes — PSU-0261-12A is the model number and 3KXG758003U0400 is the ABB catalog part number for the same unit. They are identical.
Q: Is this module compatible with ABB AC800M controllers?
A: Compatibility depends on the specific rack revision. Please contact us with your system serial number for confirmation before ordering.
Q: What happens if I install a higher-current PSU (e.g., 15 A) in place of the 12 A model?
A: A higher-rated PSU will generally work if the voltage and connector match, but always verify with ABB system documentation. Over-specification is usually safe; under-specification is not.
Q: Do you offer refurbished units?
A: Yes. Refurbished units are clearly labeled, fully tested, and carry the same 12-month warranty. Contact us for pricing.
Q: How long does shipping take to Europe / North America?
A: Typically 3–7 business days via DHL Express from our warehouse in China.
Q: Can you provide a certificate of conformity or test report?
A: Yes, available on request for all orders. Please note this in your order comments or email us after purchase.
