Product Introduction (No Fluff)
The Emerson is a critical DC/DC power supply module designed for the DeltaV distributed control system. It converts incoming power to stable 12/24 VDC outputs required to operate various DeltaV I/O cards, controllers, and communication modules within the rack.
Sourcing this exact OEM replacement part prevents system-wide failures caused by degraded power regulation. Keeping verified new surplus stock on hand drastically reduces unplanned downtime during critical power supply failures or when expanding DeltaV system capacity.
QA & Testing SOP (Dynamic & Transparent)
Power supplies are the foundation of any control system and demand rigorous validation. Every undergoes an inbound anti-counterfeit inspection, verifying Emerson/DeltaV factory labels and PCB markings. Next, the module is tested on a dedicated DeltaV test bench to validate output voltage regulation under load. We perform a full load-bank test to verify 12/24 VDC stability and check ripple voltage to ensure clean power for sensitive control modules. Finally, a continuous burn-in catches marginal capacitors or switching components before they reach your panel. All units ship in anti-static shielding with a printed QA test report.
Installation Pitfalls & Guide (Engineer to Engineer)
❗ Output Voltage Verification: Before installing this , verify that the output voltage selector (if present) matches your DeltaV rack requirements. Applying 24 VDC to a 12 VDC-only module can cause catastrophic damage to downstream I/O cards.
❗ Power Sequencing: DeltaV systems often have specific power-up and power-down sequences. Always follow the DeltaV hardware manual for proper power sequencing to prevent backplane communication errors or module initialization failures.
❗ Thermal Management: Power supplies generate significant heat. Ensure adequate airflow across the module and verify that adjacent modules are not obstructing ventilation. Overheating is a primary cause of premature power supply failure.
❗ Redundancy Configuration: If your DeltaV system supports redundant power supplies, verify that both units are properly configured and that the redundancy monitoring circuit is functional before relying on backup power.
Replacement Protocol:
- Pre-Install: Lock out the DeltaV rack power. Verify 0 VDC at the backplane. Ground yourself properly.
- Removal: Release the front panel retaining screws. Extract the failed straight out. Inspect the backplane connector for bent pins or burn marks.
- Install: Align the new with the guides. Seat it firmly and secure the faceplate screws. Verify all connections are tight.
- Power-on Test: Restore rack power. Verify the “OK” or “Power Good” LED illuminates. Use DeltaV Explorer or configuration software to validate power supply status and voltage readings. Confirm no rack faults are active.

Technical FAQ
Yes, the maintains complete backward compatibility with existing DeltaV racks. It provides the same 12/24 VDC output and integrates seamlessly with DeltaV system monitoring. You can swap it directly without reconfiguring the entire system.
Why is this listed as “New Surplus” instead of factory-new?
This is genuine Emerson DeltaV stock that was never deployed in a plant or refinery. It has been stored in climate-controlled inventory rather than exposed to harsh industrial environments. You receive the exact same MTBF and lifespan as a factory-fresh unit, typically at a significantly lower cost and without extended OEM lead times.
Can I hot-swap this power supply while the DeltaV rack is live?
This depends on your specific DeltaV rack configuration and whether redundant power supplies are installed. Always consult the DeltaV hardware manual before attempting hot-swap. If this is your only power supply, removing it will cause an immediate rack shutdown. Never assume hot-swap capability without verification.
What is the warranty coverage on this part?
We provide a standard 12-month functional warranty. If the power supply fails under normal operating conditions within that window, we replace it. Our QA testing proves the module delivered stable 12/24 VDC under load before it left our bench, so we stand behind our inventory.
My DeltaV rack is losing power intermittently. Is this PSU bad?
Not necessarily. Before replacing the , check the input voltage for sags or transients. Verify the backplane connectors are tight and free of corrosion. Intermittent power loss can also be caused by a failing downstream module drawing excessive current. Only replace the PSU if load-bank testing confirms it cannot maintain regulation under nominal load.
