Features

Dual Redundant Channels

Two independent power channels operate in parallel, with automatic failover if one channel fails. This eliminates single points of failure, ensuring continuous power to 3500 system modules even during component faults.

Wide Input Voltage Range

Auto-switching 115/230 VAC input adapts to global facility power standards, supporting deployment in regions with varying electrical grids.

Comprehensive Protection Mechanisms

Overcurrent, overvoltage, and short-circuit protection shield 3500 modules from electrical faults, while thermal shutdown prevents damage from overheating.

Hot-Swappable Design

Channels can be replaced without powering down the system, enabling maintenance during operation and minimizing downtime for critical assets.

Stable Voltage Regulation

Tight output regulation (±0.5 VDC) ensures consistent power delivery to sensitive components like vibration sensors and microprocessors, maintaining measurement accuracy.

Function

The primary function of the 3500/05-01-02-00-00-00 is to supply regulated, redundant 24 VDC power to all modules in the Bently Nevada 3500 system rack. It converts incoming AC power from the facility into clean DC power, filtering out electrical noise to prevent interference with sensitive monitoring equipment. Its dual redundant channels operate in parallel under normal conditions; if one channel fails, the other immediately ramps up to full load, ensuring uninterrupted power. Built-in protection features detect anomalies (e.g., overloads, voltage spikes) and isolate faults, preventing damage to downstream modules.

Use

In industrial settings, the module is installed in the bottom slot of the 3500 system rack, where it connects to facility AC power via dual inputs (for redundancy). It distributes 24 VDC power to rack-mounted modules, including vibration monitors, speed sensors, and communication interfaces. LED indicators on the front panel provide at-a-glance status of each channel, allowing operators to quickly identify faults. During maintenance, faulty channels can be hot-swapped to restore full redundancy without interrupting system operation, ensuring continuous machinery protection.

Application Fields

Power Generation

Provides redundant power to turbine, generator, and pump monitoring systems in coal, gas, and nuclear power plants. Uninterrupted power ensures continuous vibration and position monitoring, critical for preventing turbine failures and maintaining grid stability.

Oil and Gas

Powers compressor, pipeline pump, and gas turbine monitoring modules in upstream drilling, midstream pipelines, and downstream refineries. Its rugged design withstands corrosive and high-temperature environments, supporting reliable operation in remote oil fields.

Chemical Processing

Supplies stable power to reactor, mixer, and agitator monitoring systems. Redundant power ensures continuous tracking of machinery health, preventing process disruptions and hazardous material leaks in chemical plants.

Mining and Metals

Withstands dust and vibration in mining operations to power crusher, conveyor, and mill drive monitoring systems. Uninterrupted power ensures early detection of bearing wear and imbalance, minimizing downtime for ore processing equipment.

Pulp and Paper

Ensures reliable power to paper machine roller and motor monitoring modules. Stable power delivery supports continuous vibration analysis, maintaining product quality by preventing misalignment-related defects in paper production.

In summary, the Bently Nevada 3500/05-01-02-00-00-00 is a vital redundant power supply module that forms the backbone of the 3500 system’s reliability. Its redundant design, protection features, and global compatibility make it essential for industries where uninterrupted machinery monitoring is critical to safety, productivity, and operational efficiency.
