Product Introduction: 3500/15-05-05 Power Supply
The 3500/15-05-05 is a fundamental component of the Bently Nevada 3500 Machinery Protection System. It is a 24 VDC Input Redundant Power Supply module. Its primary function is to convert an external 24 VDC power source into the clean, regulated +15 VDC, -15 VDC, and +5 VDC voltages required to operate all the monitoring, relay, and communication modules within a 3500 rack. This model is specifically designed for industrial environments where 24 VDC is the standard control voltage, often sourced from power supplies connected to DC UPS systems or plant-wide 24 VDC distribution. A key feature is its support for redundant (N+1) operation, ensuring the continuous and fail-safe operation of the entire machinery protection system even if one power supply module fails.

Application Scenarios
The 3500/15-05-05 is deployed in a wide range of industrial settings where 24 VDC is the preferred or available power source for control and instrumentation systems.
General Industrial Machinery Protection:
Provides primary power for 3500 racks monitoring critical assets such as compressors, pumps, fans, and motors in industries like oil & gas, chemical, and water treatment, where 24 VDC is a common control system voltage.
Packaged Equipment and Skids:
Ideal for OEM (Original Equipment Manufacturer) skids and packaged compressor or pump sets. These often have their own 24 VDC control panels, and the 3500/15-05-05 integrates seamlessly without requiring an additional AC power source.
Systems with Modular DC UPS Backup:
Frequently used in setups where the entire monitoring system is backed by a compact 24 VDC Uninterruptible Power Supply (UPS). This ensures the machinery protection system remains online during a main power failure, allowing for a safe and controlled shutdown.
Remote or Distributed I/O Applications:
Suitable for applications where the 3500 rack is located away from the main control room and is powered by a locally distributed 24 VDC power bus, simplifying wiring and improving compatibility with other DC-powered instruments.
