Product Introduction & Supply Chain Strategy
The Bently Nevada 3500/15 is a half-height power supply module designed to convert line AC or plant DC power into the regulated voltages required by all monitoring modules in the 3500 Machinery Protection System. It installs on the far-left side of the 3500 rack and supports dual-redundant configurations, ensuring continuous, uninterrupted machinery protection for critical turbines, compressors, and large rotating assets.
Maintaining a 3500/15 power supply as a New Surplus unit on site is a high-priority insurance policy against catastrophic plant trips. Purchasing genuine Original New Surplus eliminates the hidden failure risks associated with aged electrolytic capacitors in second-hand units. This strategy guarantees OEM-level reliability, maintains low Total Cost of Ownership (TCO), and protects against costly stock-out downtime on critical turbomachinery racks.
Installation & Configuration Guide
Stage 1: Pre-Installation (Prep & Safety)
- Verify power supply input voltage rating matches your utility feed (Universal AC, High Voltage DC, or Low Voltage DC).
- Disconnect field circuit breakers and apply Lock-Out/Tag-Out (LOTO) procedures.
- Put on a grounded ESD wrist strap before handling the 3500/15 module.
- Ensure the associated Power Input Module (PIM) is correctly installed in the rear slot directly behind the power supply slot.
Stage 2: Removal
- Unscrew the top and bottom captive retaining screws on the front panel of the existing module.
- Unlatch the ejector handles and pull the module straight out along its rack guides to prevent backplane pin damage.
- Inspect the slot connector for dust or physical obstruction.
Stage 3: Installation (Clone & Seat)
- Slide the replacement 3500/15 module smoothly into the left-side half-height slot along the rack guide rails.
- Firmly seat the module by pushing the ejector handles fully inward until flush with the front panel.
- Tighten top and bottom retaining screws to secure the chassis connection and complete the ground bond.
Stage 4: Power-On & Testing
- Energize the primary power feed to the rear Power Input Module (PIM).
- Observe the front panel “Supply OK” LED indicator; a solid green LED confirms output rails are regulated properly.
- In redundant dual-supply configurations, verify both primary (lower) and backup (upper) module LEDs indicate operational status without fault codes.

Firmware/Software Versions & Upgrade Notes
- Hardware Compatibility Notice: Universal AC power supply modules (e.g., P/N 106M1079-01) must be paired with Universal AC Power Input Modules (PIM P/N 106M1081-01). They are not backward compatible with legacy High Voltage AC or Low Voltage AC PIMs.
- Firmware Dependencies: The 3500/15 module operates on hardware logic; no software or firmware download is required directly into the module.
- System Rack Interface: Ensure the 3500 Rack Interface Module (RIM 3500/22M) or Transient Data Interface (TDI 3500/20) firmware recognizes your rack configuration for correct power supply status reporting over System 1 software.
- Hot-Swap Protection: The 3500/15 supports live insertion/removal under power provided a second functional 3500/15 power supply is active in the rack. Never remove both supplies simultaneously on an operating machine protection rack.
Frequently Asked Questions (FAQ)
Is this 3500/15 unit brand new, or is it a pulled/refurbished module?
This product is a Brand New Surplus unit. It is not used, not pulled from a decommissioned plant, and not refurbished. All modules undergo rigorous quality verification to ensure OEM-level reliability.
Why shouldn’t I buy a cheaper refurbished 3500/15 power supply on the secondary market?
Refurbished power supplies frequently suffer from thermal degradation of internal electrolytic filter capacitors and hidden transformer fatigue. If a refurbished supply fails in a single-supply rack, it causes an ungraceful shutdown of the entire machinery protection system, which can trigger an emergency trip on multimillion-dollar turbomachinery assets.
Can I run two different input types (e.g., AC in the primary slot and DC in the backup slot) in the same 3500 rack?
Yes. The 3500 rack supports any combination of AC and DC power supplies in the upper and lower left slots. Either individual supply is capable of powering a fully loaded 3500 rack independently.
How does primary and backup power supply switching work in a dual 3500/15 setup?
When two power supplies are installed, the module in the lower slot acts as the primary supply, while the upper slot supply acts as the backup. If the primary supply loses input power or fails internally, the backup supply instantly assumes the full rack load without interrupting system operation or data collection.
What warranty and quality verification backs this New Surplus supply?
Every 3500/15 unit undergoes physical visual inspection, serial number verification, and live functional bench testing prior to shipment. We back our New Surplus inventory with a comprehensive 1-year replacement warranty to guarantee complete peace of mind.
