Why Choose the Original Model
- OEM-certified design – Engineered to Rockwell Automation’s exact electrical and thermal specifications
- Firmware compatibility – Guaranteed compatibility with the original drive’s control logic and diagnostics
- Reduced commissioning risk – No re-parameterization or adaptation required
- Long-term support – Backed by Rockwell’s global service network and spare parts ecosystem
- Traceability – Full manufacturing traceability for regulated industries (food, pharma, energy)
Typical Applications
- Allen-Bradley PowerFlex and legacy drive series power supply replacement
- PLC rack power supply board repair and refurbishment
- Industrial automation panel maintenance and emergency spare
- OEM machine rebuild and retrofit projects
- MRO (Maintenance, Repair & Operations) inventory for manufacturing plants
System Compatibility
This board is associated with Allen-Bradley / Rockwell Automation control and drive platforms. Typical compatible systems include:
- Allen-Bradley PowerFlex drive series (confirm specific model with Konmask)
- 1747 / 1756 / 1771 PLC platform ancillary power assemblies
- Legacy Bulletin 1336 and 1395 drive systems
Important: Always cross-reference the board’s revision suffix (e.g., -04) with your system’s BOM or service manual before installation.
Selection Guide
Use the following decision framework to select the correct part:
- Identify your drive/PLC model number – Found on the nameplate or inside the enclosure door.
- Confirm the board revision – The suffix (-04 in this case) indicates a specific hardware revision. Mismatched revisions may cause faults.
- Determine condition requirement – New OEM for critical uptime applications; tested refurbished for budget-constrained MRO.
- Check lead time vs. downtime cost – Konmask maintains stock for rapid dispatch; contact us for same-day shipping availability.
- Evaluate third-party alternatives – Only if OEM is discontinued or lead time is unacceptable; request a compatibility datasheet.
