Product Information:

The Bently Nevada 125840-01 is a rear-mounted hardware component called the High Voltage AC Power Input Module (PIM). It resides within the Bently Nevada 3500/15 power sub-assembly, which forms the foundation power supply for the entire 3500 mechanical protection system rack. The 125840-01 PIM acts as a physical junction box, directly connecting the equipment's power supply to the rack.

This module preprocesses the input AC power before transmitting it to the main power module and supports single/dual redundant power supply configurations to ensure continuous and stable rack operation under uninterrupted hot-swapping. The module is certified for hazardous environments such as CSA and ATEX Zone 2, providing highly reliable and stable power in harsh industrial environments.

Information

Overview Manuals Principle Primary Applications

Features:

  • High Voltage AC Power Input Module
  • 3500/15 AC and DC Power Supplies
  • Uses the High Voltage DC Power Supply and the High Voltage DC Power Input Module (PIM)
The Bently Nevada 3500/15 AC and DC Power Supplies are half-height modules and must be installed in designated slots on the left side of the rack. The 3500 rack can contain one or two power supplies with any combinations of AC and DC. Either supply can power a full rack.

When two power supplies are installed in a rack, the one in the lower slot acts as the primary supply, and the other in the upper slot acts as the backup supply. If installed, the second supply is the backup for the primary one. Removing or inserting either power supply module does not disrupt operation of the rack as long as a second power supply is installed.

The 125840-01 Bently Nevada High Voltage ac Power Input Module may still be available for purchase and support from Moore Automated Company beyond End-Of-Life (EOL) by the manufacturer (OEM).
Bently Nevada 125840-01 High Voltage ac Power Input Module Manuals(Datasheets), Link Important Notice: Other accessories, manuals, cables, calibration data, software, etc. are not included with this equipment unless listed in the above stock item description. All prices are shown in USD.
The 3500/15 AC and DC Power Supplies accepts a wide range of input voltages and converts them to voltages acceptable for use by other 3500 modules. The following power supplies are available with the 3500 Series Machinery Protection System:Universal AC Power/High Voltage DC Power Supply/Low Voltage DC Power Supply
Machinery Protection Systems: Serving as the main power gateway for the 3500 Series Machinery Protection System, it provides stable power to critical monitoring modules for turbines, compressors, and pumps.
Redundant Power Configuration: The rack can accommodate two power supplies. In this configuration, the 125840-01 supports high availability applications, allowing a PIM module to be removed or inserted without interrupting monitoring of operating machinery, even with a second power supply available.
Industrial Grid Integration: Designed for areas or facilities using higher AC voltages, it accepts an input voltage range of 175 to 264 Vac rms.
Hazardous Environments: Certified for use in Class I Zone 2 (Groups A-D) environments, suitable for oil, gas, and chemical processing plants.

Technical notes

The Bentley Nevada 125840-01 is a high-voltage AC power input module (PIM) designed for 3500/15 power systems. This half-height module, mounted at the rear of the monitoring rack, accepts external high-voltage AC power from 175 to 264 Vac rms. It integrates critical electrical isolation protection and fuse-based overvoltage protection.
