Solving the Discontinued Hardware Crisis

Honeywell formally discontinued the TDC 3000 product line, and replacement parts for the power distribution subsystem — including the 2MLP-ACF1-CC — have not been manufactured for years. Yet thousands of process units worldwide continue to operate on this platform. The power supply layer is the most failure-prone subsystem in any aging DCS cabinet: electrolytic capacitors degrade, inrush current protection circuits weaken, and thermal cycling over 15 to 25 years of continuous operation takes a measurable toll on component reliability.

Condition & Reliability Assurance

Every 2MLP-ACF1-CC unit shipped by DriveKNMS passes a structured 5-step quality process before dispatch:

• Step 1 – Electrolytic Capacitor Assessment: Visual and electrical inspection for capacitor bulging, leakage, and ESR degradation — the primary failure mode in aged power supply modules.
• Step 2 – Firmware & Configuration Verification: Where applicable, firmware version is confirmed against known-compatible TDC 3000 / TPS system revisions.
• Step 3 – Pin and Connector Inspection: All edge connectors and backplane pins are inspected for oxidation, corrosion, and mechanical deformation. Affected contacts are cleaned and treated.
• Step 4 – Functional Power-On Test: Unit is powered and output rails are measured against specification tolerances.
• Step 5 – Packaging for Long-Term Storage: Units are packed in anti-static, moisture-barrier packaging suitable for extended shelf storage in maintenance stores.

Key Features for System Maintenance

• Drop-in replacement: The 2MLP-ACF1-CC installs directly into the existing TDC 3000 / TPS cabinet backplane with no hardware modification.
• No reprogramming required: Power supply modules in this series carry no user-configurable firmware. Replacement requires no DCS engineering intervention.
• No system reconfiguration: Controller nodes and I/O assignments are unaffected by a power supply swap, eliminating the need for costly re-engineering or re-validation.
• Avoids forced migration: Maintaining operational power distribution hardware keeps the existing DCS investment productive and defers the capital cost of platform migration.

How do I know the unit is genuine and not counterfeit?
All units are sourced through documented supply chain channels. Physical markings, label formats, and board-level construction are verified against known-authentic reference units. We do not source from unverified brokers.
