The Bently Nevada 129478-01 is a High Voltage DC Power Input Module designed for the 3500/15 Power Supply series. This module provides regulated high-voltage DC power to the 3500 machinery protection rack system, ensuring the stable operation of critical monitoring modules in industrial environments such as turbines, compressors, and other rotating equipment. The module is engineered for high-availability applications, supporting redundant power supply configurations to maintain continuous system monitoring even in the event of a single supply failure.
Features
Designed for integration into the 3500 rack system, occupying half-height slots on the left side of the chassis.
Supports redundant power configurations where two modules can be installed to provide seamless backup.
Accepts a high voltage DC input range of 180 to 350 VDC.
Provides regulated outputs to power all modules within the 3500 rack.
Compatible with various 3500/15 power supply configurations.
Applications
This power input module is intended for use in Bently Nevada 3500 series machinery protection systems. It is commonly deployed in power generation, oil and gas, and petrochemical facilities to ensure reliable power for vibration and process monitoring instrumentation on critical rotating machinery.
