Advantages and Features
- Redundant Power Input: BENTLY 129486-01 supports dual AC/DC input channels, ensuring continuous power delivery to the 3500 rack if one input fails—critical for uninterrupted monitoring of critical machinery.
- Precision Voltage Regulation: ±1% output voltage accuracy and ±0.5% load regulation prevent voltage fluctuations that could damage sensitive 3500 Series modules or distort sensor data.
- Comprehensive Protection: Built-in overvoltage, overcurrent, short-circuit, and over-temperature protection safeguards both the power supply and connected 3500 components, reducing downtime from electrical faults.
- Hot-Swappable Design: In redundant configurations, BENTLY 129486-01 can be replaced while the 3500 rack remains operational, eliminating system downtime for maintenance or module replacement.
- Wide Input Voltage Range: 100-240 VAC/120-300 VDC input compatibility allows use in global industrial environments with varying power grid standards, reducing the need for external voltage converters.
- Hazardous Area Compliance: ATEX/IECEx certification enables installation in Zone 1 explosive environments (refineries, chemical plants), meeting strict safety requirements for high-risk applications.
Application Fields and Cases
Core Application Fields
- Power Industry: Turbine generator monitoring system power supply, boiler feed pump condition monitoring rack power
- Petroleum and Chemical Industry: Refinery compressor 3500 Series rack power, pipeline pump vibration monitoring system power
- Metallurgical Industry: Blast furnace blower control rack power, rolling mill main drive monitoring system power
- Marine Engineering: Offshore platform gas compressor monitoring rack power, ship propulsion system condition monitoring power
Typical Application Case
In a 500MW coal-fired power plant’s steam turbine monitoring project, the plant deployed two BENTLY 129486-01 modules in redundant configuration to power the 3500 Series rack (housing 3500/40M vibration modules and 3500/25 Keyphasor modules). During a grid voltage surge, one input channel of BENTLY 129486-01 triggered overvoltage protection and automatically switched to the redundant input, ensuring uninterrupted power to the monitoring system. The module’s overcurrent protection also prevented damage to the 3500 rack when a faulty sensor caused a short circuit, allowing maintenance teams to resolve the issue without shutting down the turbine. BENTLY 129486-01’s reliable performance reduced unplanned downtime by 90% for the turbine monitoring system, saving the plant approximately $300,000 in potential losses [Product Link: Please supplement] (see the project’s power supply reliability report and fault log data).

Selection Suggestions
- System Compatibility: Prioritize BENTLY 129486-01 for Bently 3500 Series racks to ensure optimal power matching and protection; choose universal power supplies only for non-critical auxiliary systems.
- Redundancy Planning: Deploy two BENTLY 129486-01 modules in redundant configuration for critical machinery (turbines, compressors) to eliminate single points of failure in power supply.
- Environment Matching: Use ATEX-certified BENTLY 129486-01 in Zone 1 hazardous areas; standard versions are suitable for non-explosive industrial environments.
- Load Capacity: Calculate total load of the 3500 rack (sum of all module power draws) and select BENTLY 129486-01 (10A continuous) or higher-capacity variants for racks with >8 modules.
- Spare Parts Reserve: Reserve one BENTLY 129486-01 module per 5 3500 racks to ensure quick replacement in case of failure, especially for remote or hard-to-access installations.
Precautions
- Install BENTLY 129486-01 in the designated power supply slot of the 3500 rack and ensure secure connection of input/output cables to avoid loose connections or voltage drops.
- Configure redundant input channels with separate power sources (e.g., main grid and UPS) to maximize reliability—never connect both inputs to the same power circuit.
- Avoid overloading the module beyond its 10A continuous output rating; distribute loads evenly across redundant modules if the rack exceeds 10A total power demand.
- Perform hot-swapping only when the redundant module is active and supplying power to the rack; wear an anti-static wristband to prevent static damage to internal components.
- Regularly inspect the module’s cooling fan (if equipped) and clean air vents to prevent overheating—replace the fan every 3 years or as recommended by Bently’s maintenance guidelines.
- Store spare modules in a dry, temperature-controlled environment (-20°C ~ 50°C) with anti-static packaging to prevent moisture damage or electrostatic discharge (ESD).
