Description

The Bently Nevada 125840-01 is a High Voltage AC Power Input Module (PIM) designed for integration with the 3500/15 Power Supply Module within the Bently Nevada 3500 Machinery Protection System. This module serves as the primary interface for high-voltage AC input power, conditioning the electricity to meet the specific requirements of the 3500 series rack. It ensures stable, reliable operation for all monitoring, communication, and protection modules installed in the system.

Features

• Designed for high-voltage AC input applications (175 to 264 VAC).
• Half-height module form factor, optimized for the 3500 rack power supply slots.
• Supports redundant power configurations when paired with a second 3500/15 power supply.
• Hot-swappable capability allows for module replacement without interrupting rack operation, provided a redundant supply is active.
• Integrated power factor correction and inrush current limiting for system stability.

Applications

• Power Generation: Nuclear, fossil fuel, hydro, and wind facilities.
• Oil & Gas: Refineries, offshore platforms, and petrochemical processing plants.
• Marine: Propulsion system monitoring and auxiliary machinery control.
• Compressors: Centrifugal and reciprocating compressor monitoring.
• Turbines: Steam, gas, and hydro turbine generator protection.

Technical Specifications

Installation Guidelines

• The 125840-01 must be installed in the dedicated power supply slots on the left side of the 3500 rack.
• Ensure the rack is powered down before physical installation or removal, unless performing a hot-swap in a redundant configuration.
• Use appropriate ESD protection when handling the module to prevent damage to internal circuitry.
• Verify that the input voltage matches the module rating (High Voltage) before applying power.
• Ensure proper ventilation around the rack to maintain operating temperatures within the specified range.

FAQ

What is the function of the 125840-01?

It serves as the AC input interface for the 3500/15 power supply, converting AC line power to a voltage usable by other 3500 modules.

Is this module hot-swappable?

Yes, when two power supply modules are installed (serving as a backup for each other), you can remove or insert the module without disrupting the rack's operation.

What is the difference between 125840-01 and 125840-02?

The 125840-01 is designed for High Voltage AC inputs, whereas the 125840-02 is specifically for Low Voltage AC applications.
