Description
Bently Nevada 3500/15 106M1079-01 Power Supply Module
The Bently Nevada 3500/15 (specifically the 106M1079-01 high-voltage AC/DC variant) is a half-rack module designed to provide regulated power to the 3500 Machinery Protection System. It is the primary energy source for the rack’s backplane, ensuring that all monitoring modules, such as vibration, position, and speed monitors, receive stable and noise-free power.
Product Introduction
The 106M1079-01 is a high-voltage power supply that converts input line voltage into the specific DC levels required by the 3500 rack components. The 3500/15 system is designed for high availability; a single rack can house two power supply modules in a redundant configuration. If one supply fails, the second immediately takes over the full load without interrupting the rack’s monitoring functions.

Product Technical Description
- Voltage Regulation: Advanced switching circuitry maintains precise output levels despite fluctuations in the primary utility power.
- Redundancy Logic: The module includes steering diodes and monitoring circuits that allow two supplies to be tied to the same backplane. The “Supply OK” relay indicates the health of the individual module.
- EMI/RFI Filtering: Built-in filters prevent electromagnetic interference from the power line from affecting the sensitive analog measurements of the vibration monitors.
- Self-Diagnostics: The module continuously monitors its own internal voltages and temperatures, triggering a “Power Supply Failure” alarm if parameters fall out of range.
Instructions for Use
- Installation: Slide the module into the power supply slot (located on the far left of the 3500 rack). Redundant systems use both the upper and lower supply slots.
- Wiring: Connect the AC or DC input to the corresponding terminals on the 127610-01 (High Voltage) Power Input Module located at the rear of the rack.
- Grounding: Ensure the rack is properly grounded to the plant safety earth to prevent noise and ensure safety.
- Redundancy Check: If two modules are installed, verify that both “Supply OK” LEDs on the front panel are illuminated green.
- Hot-Swapping: A single power supply can be replaced while the rack is powered (provided a redundant supply is present and active).
Product Q&A
- Q: Can I mix High Voltage and Low Voltage supplies in the same rack?
- A: No. Both power supply modules in a redundant configuration must be of the same type (both High Voltage or both Low Voltage) and must use the matching Power Input Module (PIM).
- Q: What does the “Supply OK” LED indicate?
- A: A green LED indicates the module is producing all required output voltages within tolerance. If the LED is off, the module or the input power has failed.
- Q: Is there a specific slot for this module?
- A: Yes, the 3500/15 must be installed in the dedicated power supply slots on the left-hand side of the rack.
