Product Description

Overview

The 106M1081-01 from Bently Nevada is a half-height Universal DC Power Supply Module designed for the 3500/15 Machinery Protection System. It converts a wide-range DC input into precise regulated voltages to power the rack’s backplane and connected modules, ensuring continuous operation of mission-critical machinery protection systems.

Engineered for industrial DC environments, this module supports full redundancy and hot-swappable installation, enabling uninterrupted protection even if a module is removed or one power source fails.

Key Features

Wide-Range DC Input

• Accepts 88–140 Vdc, accommodating standard 110 Vdc and 125 Vdc industrial power systems.

• Designed to tolerate typical voltage fluctuations in battery-backed DC installations.

Redundancy and Hot-Swap Capability

• Dual-module configurations allow seamless backup in case of failure.

• Modules automatically share load to maintain uninterrupted rack power.

Advanced System Protection

• High electrical isolation protects sensitive backplane electronics from noise, surges, or transient events.

• Front-panel LEDs indicate Supply OK and Low/High Voltage alerts for quick troubleshooting.

Industrial-Grade Construction

• Advanced DC-DC conversion ensures high efficiency with minimal heat generation.

• Rated for -30°C to +65°C (-22°F to +150°F) operation.

• Half-height form factor fits designated power supply slots on the left side of the 3500 rack.

Installation Notes

• Must be paired with the corresponding DC Power Input Module (PIM) at the rear of the rack.

• Can be combined with an AC supply (106M1079-01) for mixed-source redundancy.

• Not compatible with legacy high-voltage or low-voltage AC/DC modules or PIMs.

Technical Specifications

Applications

Ideal for industrial facilities using DC power systems, the 106M1081-01 is suitable for:

• Battery-backed machinery protection systems

• Continuous monitoring of motors, turbines, and compressors

• Redundant power configurations requiring hot-swappable reliability

FAQ

Q: Can this module be removed while the rack is live?
A: Yes, if a second power supply is installed, the module can be hot-swapped without interrupting operation.

Q: Is the 106M1081-01 compatible with AC power supplies?
A: Yes, it can share a rack with a 106M1079-01 AC module for mixed-source redundancy.

Q: What is required for proper installation?
A: A dedicated DC PIM must be installed behind the module to terminate the DC input.
