Series
The 136188-01 is an integral part of the Bently Nevada 3500 series, a comprehensive suite of machinery protection and condition monitoring solutions. The 3500 series includes modular components such as vibration monitors, communication modules, I/O modules, and power supplies, all engineered for seamless integration. Renowned for scalability, redundancy, and compliance with global standards (e.g., API 670), the series is trusted worldwide to protect critical rotating machinery in industries such as power generation, oil & gas, and chemical processing. The 136188-01 enhances the series by providing reliable power infrastructure, ensuring continuous operation of the 3500 system’s monitoring capabilities.
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 uninterrupted power to the 3500 system.
Wide Input Voltage Range
100–240 VAC input compatibility supports global deployment, adapting to varying facility power grids in different regions and industries.
Comprehensive Protection Mechanisms
Overload, short-circuit, and over-voltage protection prevent damage to 3500 modules during electrical anomalies, enhancing system durability.
Hot-Swappable Design
Channels can be replaced without powering down the system, enabling maintenance during operation and minimizing downtime.
High Efficiency and Regulation
85% efficiency reduces energy waste, while tight output voltage regulation (±0.5 VDC) ensures stable power for accurate sensor and module operation.
Function
The primary function of the 136188-01 is to supply regulated and redundant 24 VDC power to all modules in the 3500 system rack. It converts incoming AC power from the facility into clean DC power, filtering out electrical noise and transients to protect sensitive monitoring components. Its dual-channel design operates in parallel under normal conditions, sharing the load; if one channel fails, the other automatically ramps up to full capacity to maintain power supply. Built-in diagnostics monitor voltage levels, current draw, and channel health, with fault alerts transmitted to the 3500 system for operator notification.
Use
In industrial settings, the module is installed in the bottom slot of the 3500 system rack, connected 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 real-time 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 plants, ensuring uninterrupted protection of assets critical to electricity production and grid stability.
Oil and Gas
Powers compressor, pipeline pump, and gas turbine monitoring modules in upstream drilling, midstream transportation, and downstream refining operations, supporting safe hydrocarbon processing in remote and harsh environments.
Chemical Processing
Supplies stable power to reactor, mixer, and centrifuge monitoring systems, withstanding corrosive atmospheres and temperature fluctuations to prevent process disruptions.
Pulp and Paper
Delivers reliable power to paper machine roller and motor monitoring modules, maintaining consistent operation of condition monitoring systems to optimize production efficiency.
Metals and Mining
Withstands rugged conditions in mining operations to power crusher, conveyor, and mill drive monitoring systems, ensuring uninterrupted protection of critical mining equipment in dusty and vibration-prone environments.
In summary, the Bently Nevada 136188-01 is a vital power supply module that underpins the reliability of the 3500 Machinery Protection System. Its redundant design, robust protection features, and global compatibility make it essential for industries where uninterrupted machinery monitoring is critical to safety, productivity, and operational efficiency.
