Bently Nevada 115M7750-01 3500/15 High Voltage DC Power Input Module

Description

The 115M7750-01 High Voltage DC Power Input Module (PIM) is a rear-mount power interface component designed for the Bently Nevada 3500/15 AC and DC Power Supplies system. Installed directly behind the corresponding front-facing power supply module, the 115M7750-01 provides the primary high-voltage DC power connection and input conditioning for the 3500 Series Machinery Protection System rack.

It connects an external high-voltage DC source to the front-facing 114M5329-01 High Voltage DC Power Supply Module. This allows incoming voltage to be safely routed and converted for internal rack utilization.

Features

• Accepts a high-voltage DC input range from 88 Vdc to 140 Vdc.
• Uses a half-height rear module footprint directly behind the associated power supply.
• Works with the 3500/15 High Voltage DC Power Supply Module, part number 114M5329-01.
• Includes onboard fuse protection against over-voltage conditions.
• Under-voltage conditions do not damage the module or power supply.
• Supports hot-swappable replacement in dual-redundant power configurations without interrupting rack operation.

Applications

• High-voltage DC-powered 3500 Series Machinery Protection System racks.
• Turbomachinery vibration and condition monitoring systems.
• Continuous machinery protection in oil and gas facilities.
• Power generation plants.
• Chemical and process industry installations.

Technical Specifications

Installation Guidelines

• Rack Location: Install the module in the special half-height slot at the rear of the rack. It must be positioned directly behind the associated front-facing 3500/15 High Voltage DC Power Supply Module.
• Redundancy Configuration: In a dual-supply system, the PIM can be inserted or replaced without interrupting rack operation, provided the second power supply remains operational.
• Wiring and Terminal Safety: Verify that the DC power connection remains within the specified 88 to 140 Vdc range. Confirm the correct polarity before applying input power.
• Protection and Fusing: An over-voltage event will cause the PIM fuse to open. Replace it only with the specified 129M0198 replacement fuse.
