Introduction
The model 3500/22-01-01-00 is a Power Supply Module for the Bently Nevada 3500 Machinery Protection System. This module is a critical system component that converts the plant's incoming AC or DC power to the precise +24 VDC and ±15 VDC levels required by all the monitoring and relay modules within the 3500 rack. The "-01-01-00" suffix defines its specific hardware configuration, which includes input voltage range, output power rating, and connector types. It is designed with redundancy capabilities, allowing a second power supply module to be installed in the same rack to ensure continuous system operation in the event of a single power supply failure.

Application Scenarios
The 3500/22 Power Supply is the foundational power source for the entire 3500 monitoring system, making it essential in all application scenarios.
Core System Infrastructure:
Installed as the primary or redundant power source in every 3500 rack, providing clean, regulated power to all vibration, position, speed, and relay modules, ensuring accurate and reliable monitoring.
Redundant Power Systems for Critical Machinery:
Used in pairs in a redundant (N+1) configuration for monitoring critical assets like turbines, compressors, and generators. This ensures that a single power supply failure does not lead to a loss of the entire machinery protection system, preventing catastrophic damage.
Plant-Wide Machinery Protection Systems:
Deployed in 3500 racks distributed throughout a facility (e.g., in oil refineries, chemical plants, power generation stations) to provide local, reliable power for the monitoring system, independent of fluctuations in the plant's main power bus.
OEM Skid-Mounted Equipment:
Integrated by Original Equipment Manufacturers (OEMs) into the control panels of compressors, pumps, and other packaged machinery to provide a self-contained and powered machinery protection system.
Retrofit and System Upgrades:
Used as a replacement for older or faulty power supply modules during system upgrades or maintenance to restore and ensure the continued reliability of the existing 3500 monitoring system.
