BENTLY 136180-01

Description

Product Description

The BENTLY 136180-01 is a critical rack-mounted power supply module designed for the Bently Nevada (Baker Hughes) 3500 series machinery monitoring system. This module is the primary source of conditioned and protected DC power for the entire 3500 rack, including all monitor modules, the system processor, and communication interfaces. The BENTLY 136180-01 converts incoming AC or DC plant power into the stable, isolated voltage rails required for the sensitive monitoring electronics to operate reliably. For comprehensive technical specifications, installation instructions, and safety guidelines, the essential resource is the official Baker Hughes Bently Nevada documentation portal for the BENTLY 136180-01. The integrity of the entire machinery protection system is fundamentally dependent on the reliable performance of the 136180-01 power supply. Its robust design, featuring redundancy and comprehensive diagnostics, is engineered to ensure continuous operation in the demanding environments of power plants, refineries, and other critical industrial facilities.

Product Parameters

• Manufacturer / Brand: Bently Nevada (Baker Hughes).
• Series: 3500 Machinery Monitoring System.
• Model / Part Number: 136180-01 (Power Supply Module).
• Function: Primary / Redundant Power Supply for 3500 Rack.
• Input Power: Typically accepts a wide range of AC input voltages (e.g., 90-264 VAC, 47-63 Hz) and may also support DC input options.
• Output Power: Provides multiple regulated DC output voltages (e.g., +5V, ±15V, +24V) to the 3500 backplane for powering all installed modules.
• Output Capacity: Rated for a specific wattage sufficient to power a fully populated 3500 rack (e.g., up to 16 or 32 slots, depending on the rack frame).
• Redundancy: Designed to be used in a redundant (N+1) configuration. Multiple 136180-01 modules can share the load in a single rack, and the system remains operational if one power supply fails.
• Hot Swappable: Engineered for insertion and removal from a live 3500 rack without interrupting the operation of the monitoring system, supporting online maintenance and replacement.
• Diagnostics: Includes comprehensive status LEDs for AC OK, DC OK, and module fault. It communicates its health status to the 3500 system frame for centralized alarm reporting.
• Form Factor: A single-slot module designed for installation in the dedicated power supply slots of a 3500 series rack.
• Cooling: May utilize internal fans or convection cooling, depending on the specific model and power rating.

Advantages and Features

• High Availability Design: Redundant, load-sharing architecture ensures uninterrupted power to the critical machinery monitoring system, preventing data loss and maintaining protection during a single power supply failure.
• Proven Reliability: Built with industrial-grade components and conservative thermal design for maximum mean time between failures (MTBF) in 24/7 operation.
• Comprehensive System Integration: Fully monitored by the 3500 system. A power supply fault generates an alarm in the system frame, alerting personnel immediately.
• Global Power Compatibility: Wide-range AC input allows for installation anywhere in the world without the need for external voltage transformers.
• Simplified Maintenance: Hot-swap capability and clear diagnostic indicators allow for quick identification and replacement of a failed unit, minimizing system downtime.

Application Cases in Industry

• Gas Turbine Protection Rack: Two BENTLY 136180-01 modules are installed in a redundant configuration to power a 3500 rack monitoring vibration, speed, and temperature on a critical Frame 7FA gas turbine in a combined-cycle power plant.
• Steam Turbine/Generator Monitoring: Provides reliable power to a 3500 system monitoring bearing vibration and eccentricity on a large steam turbine-generator set.
• Offshore Compressor Monitoring: Used on an offshore platform to power the monitoring system for gas export compressors, where high availability is essential due to the remote location.
• Pipeline Pump Station: Ensures continuous operation of the vibration monitoring system for high-power pumps in a remote pipeline station.
• Hydroelectric Unit Protection: Powers the 3500 rack monitoring bearing and guide vane vibration on large hydroelectric generators.

Comparison with Competing Products

Competing products are power supply modules from other machinery monitoring system vendors, such as EPRO (MMS 6000 series power supplies) or Schenck (Vibrocontrol power units). The BENTLY 136180-01 differentiates itself through its seamless integration and certification within the industry-standard Bently Nevada 3500 platform. Compared to a generic industrial DIN-rail power supply, the 136180-01 is specifically designed for the 3500 backplane’s electrical requirements, offers direct health reporting to the monitoring system, and supports true hot-swap redundancy. Its primary advantage is guaranteed compatibility, performance, and support within the 3500 ecosystem, which is crucial for maintaining the validation and reliability of certified machinery protection systems.

Selection Suggestions and Precautions

• Selection Suggestions:
  1. The BENTLY 136180-01 is a designated spare part for 3500 systems. Selection must be based on the exact model matching the failed unit or the original system specification.
  2. Always implement power supply redundancy (N+1) as per Bently Nevada’s system design guidelines for critical machinery protection applications. A single power supply should not be used for a fully loaded rack.
  3. Verify the input voltage rating of the module against your plant’s available power source (e.g., 120V AC vs. 240V AC).
• Precautions:
  1. Load Management: Do not exceed the total power budget of the power supply configuration. Consult the 3500 rack planning guide for the maximum allowable load based on the number and type of monitor modules installed.
  2. Redundant Power Feeds: For maximum availability, feed redundant 136180-01 modules from independent, isolated power circuits (e.g., different Uninterruptible Power Supply (UPS) branches) to eliminate single points of failure in the power source.
  3. Proper Grounding: Ensure the 3500 rack and the power supply’s ground connection are properly bonded to a solid plant earth ground to ensure safety and electrical noise immunity.
  4. Handling and Installation: While hot-swappable, always follow proper electrostatic discharge (ESD) procedures when handling the module. Ensure it is fully seated and latched in its slot.
  5. Genuine Parts and Support: Due to its critical role in machinery protection, source genuine BENTLY 136180-01 modules only from authorized Baker Hughes distributors or certified service centers. The use of non-genuine parts can compromise system reliability and safety certification. Maintain an appropriate spare on-site for critical applications.
