Product Overview

The Bently Nevada 3500/15 114M5329-01 is a high-voltage DC power supply designed to provide regulated power to the 3500 Series Machinery Protection System. This half-height module is specifically engineered for installation in the designated power supply slots on the left side of a 3500 rack. It functions as a critical energy conversion unit, transforming raw DC input into the stabilized voltages required by the rack’s monitoring modules, transducers, and communication processors.

A single 3500/15 power supply is capable of supporting a fully loaded 3500 rack. However, for applications requiring maximum availability, two modules can be installed to create a redundant power architecture. This "hot-swappable" design allows for the replacement of a failed power module without interrupting the continuous monitoring of critical rotating assets, ensuring that machinery protection remains active at all times.

Key Functional Characteristics

• Redundant Configuration Support: Supports dual-power setups where the lower module acts as the primary source and the upper module serves as the automatic backup. This configuration protects the system against single-point power failures.

• Broad Input Compatibility: Designed to operate within standard high-voltage DC utility ranges (88-140 VDC), making it ideal for power generation facilities and substations that utilize battery-backed DC buses.

• Advanced Power Conditioning: Features internal filtration and regulation to protect sensitive monitoring electronics from input voltage spikes and electromagnetic interference common in industrial power grids.

• Hot-Swap Capability: Modules can be removed or inserted into the rack while the system is energized (provided a second module is operational), facilitating maintenance without system downtime.

• Intelligent Diagnostics: Communicates its health status to the 3500/22M Transient Data Interface (TDI), allowing operators to monitor power supply integrity through the System 1 software environment.

Industrial Applications

The 114M5329-01 High Voltage DC Power Supply is a foundational component for 3500 racks deployed in:

• Fossil Fuel and Nuclear Power Plants

• Oil and Gas Refineries with DC backup systems

• Large-scale Chemical Processing Units

• Transmission and Distribution Substations
