Description
🔧 Product Overview
The Bently Nevada 129486-01 is a Legacy High Voltage DC Power Supply Module for the 3500/15 Power Supply system. It is designed for use in the Bently Nevada 3500 Series Machinery Protection System and converts the incoming DC power to the required power levels for the 3500 rack and its installed monitoring modules.
The 3500/15 power supply occupies a designated power-supply position on the left side of the 3500 rack. A rack can be configured with one or two power supplies, and AC and DC supply types can be combined where the system configuration permits. When redundant power supplies are installed, the second supply provides backup power for continued rack operation.
The 129486-01 belongs to the legacy high-voltage DC power supply family. For installations requiring the newer High Voltage DC Supply, Bently Nevada documentation also lists 114M5329-01 as the current High Voltage DC Power Supply part number.

🔌 Installation & Replacement
Before replacing a 129486-01, verify the complete 3500/15 configuration, including the power input module, rack position, and any redundant power supply.
The 3500/15 can accommodate one or two power supplies. When two supplies are installed, the lower-position supply operates as the primary supply and the upper-position supply serves as the backup. This arrangement allows a power supply module to be removed or inserted without interrupting rack operation when the redundant supply is available.
Recommended checks before installation:
- Confirm the part number on the existing module.
- Verify that the rack uses the appropriate high-voltage DC configuration.
- Check the associated Power Input Module.
- Inspect the connector and module housing for physical damage.
- Confirm the rack configuration before applying power.
- Follow the applicable Bently Nevada 3500/15 installation and safety procedures.
🏭 Typical Applications
The 129486-01 is intended for 3500 Series machinery protection installations such as:
- Steam and gas turbine monitoring
- Compressor protection
- Generator and motor monitoring
- Rotating machinery protection
- Industrial machinery condition monitoring
- Vibration monitoring systems
- Process equipment protection
- Turbomachinery control and protection cabinets
In these systems, the power supply is a basic infrastructure component: if the rack cannot maintain its required internal power, monitoring and protection functions cannot operate normally.
