Bently Nevada 3500/15 (127610-01) – Universal AC Power Supply Module for 3500 Machinery Protection Racks

The 3500/15 (P/N 127610-01) is the Universal AC Power Supply for Bently Nevada 3500 racks. It accepts a wide AC input and delivers regulated power across the backplane to every module — vibration, temperature, speed, and the TDI. From my experience, most users pair two supplies for redundancy so maintenance can service one module while the rack keeps running. You might notice that this build is “drop-in” for global mains (typically 85–264 Vac), which simplifies spares and standardization across sites.

Company’s Order Placement Process and Guarantees

• Warranty period: 365 days
• Delivery time: 1 week for in-stock, no more than one month at the latest
• Payment method: 50% advance payment, full payment for delivery
• Express delivery methods: FedEx, UPS, DHL

Key Features

• Universal AC input – Typically 85–264 Vac, 47–63 Hz, so one part number covers most plants worldwide.
• Backplane power for the entire rack – Clean, regulated DC distributed to all 3500 modules.
• Redundant-ready design – Install a second supply for automatic switchover and higher availability.
• LED status and simple diagnostics – Quick health check during commissioning and routine rounds.
• Paired with a Power Input Module (PIM) – Field wiring lands on the PIM; the supply plugs into the rack for neat cabling.
• Hot-swap in redundant configurations – Service one supply while the other maintains rack power.

Technical Specifications

Application Fields

Plants deploy the 127610-01 to standardize power across 3500 racks on:

• Steam/gas turbines and generator trains with critical vibration protection
• Compressors, expanders, and high-speed rotating equipment
• Pump and blower stations on process units where redundancy is required
• OEM skids shipped globally, benefiting from the wide AC input range

One thing I appreciate is how a redundant pair reduces anxiety during shutdowns — a customer swapped a faulty supply mid‑turnaround with no impact on their 3500 diagnostics because the second unit carried the load.

Advantages & Value

• Reliability – Proven module with clean backplane power and clear LED status.
• Compatibility – Works across the 3500 family; fits existing racks without wiring changes.
• Reduced downtime – Redundant operation enables service without shutting the rack.
• Global standardization – Universal AC input simplifies spares and site approvals.

Installation & Maintenance

• Cabinet & Ventilation – Mount the 3500 rack in a clean, ventilated enclosure; maintain ambient within spec.
• Mains Wiring – Terminate AC feed and protective earth on the Power Input Module; use proper branch protection and labeling.
• Redundancy – For critical services, install two 3500/15 supplies; verify automatic switchover and LED indications during SAT.
• Grounding & Noise – Bond the rack earth to the panel ground bar; keep mains away from low‑level transducer wiring.
• Routine Care – Periodically check terminal torque on the PIM, inspect LEDs, and record supply status during rounds.
• Change Control – If a supply is replaced, document the rack status and confirm all modules power correctly before returning to service.

Quality & Certifications

• Certifications: CE and UL/cUL; many 3500 builds are suitable for Class I, Div 2 and ATEX/IECEx Zone 2 panels (confirm per nameplate).
• RoHS compliance typically applies to current builds.
• Manufacturer’s Warranty: Standard Bently Nevada policy on new units (region dependent).
• Our Supply: 365‑day warranty as stated above.

If you’re matching an installed rack, share your PIM type, mains voltage, and redundancy preference. In most cases it’s a straight swap — usually it’s just tightening the PIM terminals and verifying LED status before handover.
