Bently Nevada 129486-01 High-Voltage DC Power Supply

Quick Overview

The 129486-01 is a High DC Power Supply Module specifically engineered for the Bently Nevada 3500 Machinery Protection System. As a primary energy source for the system, it converts high-voltage DC input into the stabilized, regulated voltages required by all other modules in the 3500 rack. 

Technical Data

• Model Number: 129486-01

• Product Type: High DC Power Supply Module

• Input Voltage: High-Voltage DC (typically 88–140 V DC or 120–373 V DC depending on rack version)

• Mounting Slot: Reserved Power Supply Slots (far left of 3500 rack)

• Shipping Weight: 5.0 kg

Key Features

• High-Efficiency Conversion: Optimizes high-voltage DC input into clean, low-noise power for sensitive vibration and seismic monitoring electronics.

• Redundancy Capability: The 3500 rack supports the installation of two power supply modules. When used in pairs, the 129486-01 provides full power redundancy, ensuring the rack stays energized if one supply fails.

• Robust Circuit Protection: Includes integrated over-voltage, over-current, and short-circuit protection to safeguard expensive monitoring modules from power surges.

• Industrial Grade Design: Built to endure the high-temperature and electrically noisy environments typical of power plants and refineries.

• Made in USA Quality: Manufactured to stringent aerospace and industrial standards, with optional Certificate of Origin (COO) available for global compliance.
