Functional Role & Application Analysis
The 3500/15 is the foundational power supply module for the Bently Nevada 3500 Machinery Protection System. It converts incoming AC or DC voltage into the precise internal voltages required by all other modules in the rack. Without this module, the entire vibration and displacement monitoring system is dead.
This component solves the critical need for uninterrupted power in safety-critical environments. The 3500/15 supports 1+1 redundancy. When two power supplies are installed, one acts as the primary and the other as a hot standby. You can remove or replace a failed power supply without powering down the rack or interrupting machine protection.
- Primary Power Source: Converts 110-220VAC or DC inputs to regulated internal bus power for the entire 3500 rack.
- Redundant Power Backup: Bottom slot acts as primary, top slot as backup. Hot-swappable design ensures zero downtime during replacement.
- Legacy System Maintenance: Replaces aging power supplies in existing 3500 installations to prevent brownouts and system resets.
- New Machinery Protection: Serves as the standard power entry point for new API 670 compliant monitoring systems.
Our Quality Standard & Testing Process
We understand that the cost of an unreliable part is far greater than its purchase price. A failed power supply means lost machine protection. We have established a rigorous, multi-stage testing process to ensure every 3500/15 we ship is 100% functional.
- Visual & Component Inspection: Technicians inspect the PCB for burnt components, leaking capacitors, and cold solder joints. We verify the LED indicators and connector pins are intact.
- Live System Test: The module is installed in a live 3500 test rack. We measure output voltage rails under full load for 24 hours to verify stability and thermal performance.
- Full-Function Diagnostics: We test redundancy failover by pulling the primary power supply while monitoring the backup. We verify seamless transition with zero voltage drop on the backplane.
- Warranty Backing: Only units passing all tests are shipped. Each 3500/15 includes a 12-month warranty against functional failure.

Compatibility & Migration Paths
To ensure this 3500/15 is 100% compatible with your system, you must verify these key points. Power supply revisions and PIM (Power Input Module) compatibility are common failure points in the field.
- Hardware Revisions & PIM Compatibility: Legacy 3500 AC/DC power supplies and PIMs are NOT compatible with Universal AC PIMs. You must match the power supply revision to your existing PIM. Check the part number suffix carefully.
- Required Components: This module requires the correct Power Input Module (PIM) mounted behind it. Verify your PIM matches your input voltage type (Universal AC, High Voltage DC, or Low Voltage DC).
- Replacement & Alternatives: The 3500/15 is a half-height module. If your rack has a full-height slot, verify you have the correct adapter or mounting hardware. Universal AC models (3500/15-05-XX) are preferred for new installations.
