Product Introduction & Supply Chain Strategy
The BENTLY 106M1081-01 is the universal AC power input module for the Bently Nevada 3500 Machinery Protection System . It converts 85–265 VAC line power to the regulated 24 VDC required by all other modules in the rack — vibration monitors, tachometers, temperature monitors, and relay modules. The 3500 system is the global standard for protecting critical rotating machinery: turbines, compressors, generators, and pumps in power generation, oil & gas, and chemical processing. This module is the lifeline of that protection system.
Procuring this module as New Surplus is a TCO-smart decision. A 3500 rack without a powered power supply is a dead system — no vibration data, no overspeed protection, no relay trips. Refurbished power modules carry significant risk: aged capacitors degrade output stability, internal components suffer thermal stress, and prior overvoltage events leave latent damage. A failed power module takes the entire monitoring rack offline. On a critical turbine or compressor, the unplanned downtime cost exceeds the module’s value by orders of magnitude. This unit offers OEM-origin traceability, zero operational hours, and a full warranty — eliminating the uncertainty of used or repaired components.

Installation & Configuration Guide
Stage 1: Pre-Installation (Prep & Safety)
- Identify the power module slot (typically the leftmost slot in the 3500 rack).
- For non-redundant systems: Lock out and tag out the 3500 rack. De-energize the AC supply to the rack.
- For redundant systems: Hot-swap is supported . Verify the second power module is operational before removal to maintain system power.
- Wear ESD wrist strap.
Stage 2: Removal
- If replacing a failed module: Visually confirm the module is powered down (LEDs off).
- Disengage the module retaining screws at top and bottom.
- Gently pull the module straight out of the slot using the extraction handle. Do not rock side-to-side.
Stage 3: Installation
- Slide the new module into the empty slot, aligning it with the guide rails.
- Press firmly until the module is fully seated in the backplane connector.
- Secure with the retaining screws.
Stage 4: Power-On & Testing
- Re-energize the AC supply (if non-redundant).
- Observe the front-panel LED indicators: The “Power” LED should illuminate .
- Verify the 3500 rack powers up and all other modules report OK status.
- Check the 3500 Rack Configuration Software for any power-related alerts.
Firmware/Software Versions & Upgrade Notes
The 106M1081-01 is a hardware power module with no user-accessible firmware or software configuration.
Version compatibility note: This module is the universal AC variant, compatible with 85–265 VAC input. It is not compatible with legacy high-voltage or low-voltage AC-only units. Always verify the input supply voltage before installation.
Critical warning: Do not attempt to open the module enclosure. There are no user-serviceable components inside. The module contains high-voltage circuits even when disconnected from AC mains for a short period.
Frequently Asked Questions (FAQ)
Q: Why is this New Surplus cheaper than Bently Nevada list price but more expensive than refurbished units?
A: The price reflects sourcing verified, OEM-origin new units from global inventory. You avoid the OEM’s full retail margin and the hidden failure risk of refurbished stock — aged capacitors and degraded isolation. The cost of a single 3500 rack failure on a critical turbine dwarfs the price difference.
Q: Is this module still active or is it EOL?
A: The 106M1081-01 remains in active production and support as the standard universal AC power input module for the 3500 system . Bently Nevada continues to manufacture the 3500 platform for its extensive global installed base.
Q: Can I hot-swap this module while the rack is powered?
A: Yes, in systems with a redundant, second power supply module installed . However, always verify the second module is operational before removal. For single-supply systems, power-down is required.
Q: What is the difference between this module and other 3500 power supplies?
A: The 106M1081-01 is the universal AC input module (85–265 VAC). It is the standard replacement for the 3500/15 power supply. Bently Nevada also offers DC input variants and legacy high/low-voltage AC units. Check your system’s input voltage before ordering .
Q: What is the warranty period and coverage?
A: The module carries a standard 1-year warranty against manufacturing defects. Coverage applies to the module hardware — not to external surges, field wiring faults, or damage from improper installation. All units are QC-tested before shipment to verify output voltage and communication handshake.
