Bently Nevada 125840-01 High Voltage Ac Power Input Module

The Bently Nevada 125840-01 is a key AC Power Input Module specifically developed for the 3500 series monitoring system. It is designed to ensure consistent and reliable power delivery by converting high voltage AC into low voltage DC, crucial for the operation of monitors and sensors within the system.

Functional Description

The 125840-01 AC Power Input Module operates as a vital component of the system's power supply mechanism:
Rack Installation:

• The system's power supplies are half-height modules that must be installed in designated slots on the left side of the rack.
• Each rack can house up to two power supplies (AC and/or DC), with one acting as the primary supply and the other as a backup.
  Voltage Options:
• Suitable for installations requiring input voltage ranging from 175 to 250 VAC RMS.
• Different configurations support either high voltage or low voltage AC options through specific input and supply modules.
  Safety Mechanisms:
• Undervoltage: Safe for both the Power Input Module (PIM) and power supply without causing damage.
• Overvoltage: Equipped with a fuse in the PIM that opens to prevent damage in case of excessive voltage.

Key Features

Efficient Power Conversion:

• Converts high voltage AC power (up to 600 VAC) into low voltage DC to power 3500 system components.
  Dual Power Supply Capability:
• Allows installation of a secondary power supply for backup, ensuring uninterrupted operation.
  Robust Safety Design:
• Incorporates a fuse mechanism to prevent damage from overvoltage scenarios.
  Environmentally Adaptive:
• Designed to handle a wide temperature range and high humidity levels.
  Versatile Configurations:
• Supports both high voltage DC and low voltage AC options depending on system requirements.
