Description
Bently Nevada 3500/15 114M5330-01 Low Voltage DC Power Supply
Product Overview
The Bently Nevada 3500/15 114M5330-01 is a Low Voltage DC Power Supply module used in the Bently Nevada 3500 Machinery Protection System. Its primary function is to accept a low-voltage DC input and provide the regulated DC power required by the modules installed in the 3500 rack. The 3500/15 is a half-height rack module installed in the designated power-supply positions on the left side of the rack. Bently Nevada documentation identifies 114M5330-01 specifically as the Low Voltage DC Power Supply, distinguishing it from the separate Power Input Module (PIM) and from the high-voltage DC and universal AC power-supply variants.
For an existing machinery protection installation, the Bently Nevada 3500/15 114M5330-01 is primarily a system-power component rather than a monitoring or communications module. It supplies the rack backplane, allowing vibration monitors, relay modules, communication interfaces, and other 3500 modules to operate from the same rack power architecture. The specified low-voltage DC input range is 20–30 VDC, with a 24 VDC-class output distributed through the rack backplane. A 3500 rack can accommodate one or two power supplies; when two are installed, the lower position functions as the primary supply and the upper position serves as the backup.
The Bently Nevada 3500/15 114M5330-01 is therefore most relevant where a plant uses a 24 VDC control-power infrastructure and requires a replacement power-supply module matching the existing 3500 rack configuration. The exact PIM and rack arrangement should be checked before procurement because the 114M5330-01 is the supply module itself, while 114M5335-01 is identified separately as the associated Low Voltage DC Power Input Module.

Main Features and Advantages
Low-Voltage DC Input Architecture
The 3500/15 114M5330-01 is intended for installations using low-voltage DC control power. Its specified 20–30 VDC input range makes it suitable for a conventional 24 VDC plant power system. This distinction is important when replacing an existing 3500/15 supply because the 3500 family includes several power-supply types with different input requirements. The 114M5330-01 should not be treated as a universal-input AC module or as the high-voltage DC version.
Rack-Level Power Distribution
The module provides power to the 3500 rack rather than directly powering an individual vibration sensor or field instrument. The supply works with the rack backplane so that installed monitoring and protection modules receive the required operating power. This makes the condition of the power supply important to the entire monitoring rack: a supply fault can affect multiple installed modules simultaneously.
Redundant Power-Supply Capability
The 3500/15 architecture supports one or two power supplies. With two supplies installed, the lower module operates as the primary supply and the upper module serves as the backup. This configuration provides a practical maintenance advantage because the rack can maintain power through a supply replacement when the required redundant arrangement is present.
Procurement and Compatibility Considerations
When purchasing a replacement Bently Nevada 3500/15 114M5330-01, verify the complete part number rather than ordering only by the 3500/15 family designation. The 3500/15 family contains multiple power-supply variants, including universal AC, high-voltage DC, and low-voltage DC versions. The associated PIM must also match the installation; Bently Nevada documentation lists 114M5335-01 separately as the Low Voltage DC PIM.
For field replacement, check the incoming DC voltage at the PIM, inspect terminal and connector condition, and confirm that the rack’s power configuration matches the intended redundant or single-supply arrangement. For used or surplus equipment, inspect the front-panel condition, connector integrity, date code, and evidence of overheating before installation. A visually clean module does not by itself establish electrical condition, so functional testing under an appropriate 3500 rack setup is preferable for critical machinery-protection applications.
Replacement Checklist
Before replacing a 3500/15 supply, verify:
- Exact part number: 114M5330-01
- Input power: 20–30 VDC
- Correct Low Voltage DC PIM
- Associated PIM part number: 114M5335-01
- Correct 3500 rack and power-supply slot
- Single- or dual-supply configuration
- Incoming DC voltage under actual plant conditions
- Connector and terminal condition
- Module date code and revision
- Functional test after installation
