Bently Nevada 106M1079-01 Universal AC Power Supply Module

Bently Nevada 106M1079-01 Universal AC Power Supply Module

The Bently Nevada 106M1079-01, also cataloged as the 3500/15 Universal AC Power Supply Module, serves as the primary hardware component utilized to execute power conversion and distribution across 3500 Machinery Protection System racks.

Hardware Specifications

Mechanical Monitoring and TSI Characteristics

The 106M1079-01 module operates as a half-height unit engineered for installation in the dedicated left-side rack slots of the 3500 system. It provides high-efficiency power conversion, transforming wide-range AC inputs into stable DC voltages required by internal 3500 monitoring modules. The system supports redundant configurations, where the lower slot module functions as the primary supply and the upper slot module serves as an automatic backup. This design ensures that removal or insertion of a single module does not disrupt rack operations, providing continuous power reliability for critical vibration and TSI data acquisition.

Frequently Asked Questions

Q: Is it possible to mix AC and DC power supplies within the same 3500 rack?

A: Yes. The 3500 rack architecture allows for combinations of AC and DC power supplies, provided they are installed in the designated slots on the left side of the rack.

Q: Does the backup power supply trigger an alarm upon switchover?

A: The 3500 system monitors the health of the power supplies. The rack configuration software reports the status of both the primary and backup supplies to operations and maintenance personnel.

Field Installation Guidelines

1. Mounting Slot: Install the module in the designated half-height slot on the left side of the 3500 rack. Ensure the module is properly oriented for the primary or backup position.

2. Power Cabling: Ensure that input power wiring is correctly terminated according to the local electrical code. Verify that the input AC supply falls within the specified 85 to 264 Vac rms range.

3. Redundancy Setup: For critical systems, install two power supply modules. The rack automatically handles the load-sharing and fail-over logic between the primary and backup units.

4. Insertion/Removal: The module supports hot-swapping. Ensure the backup supply is fully operational before removing the primary supply to guarantee uninterrupted power to the rack backplane.
