Description
The 3500/15-04-00 is a low-voltage DC power supply module designed for the Bently Nevada 3500 Machinery Protection System rack framework. This half-height module installs into the designated power supply slots on the far left side of a 3500 chassis. It steps down and regulates an incoming 20 to 30 V DC supply source into the isolated operational voltages required by the backplane to drive downstream monitoring modules, transient data managers, and transducer excitation loops.
The part number breakdown for the -04-00 suffix specifies:
- -04 (Power Supply Type): Low Voltage DC (20 to 30 V DC range)
- -00 (Agency Approval Option): None / Standard non-hazardous area configuration

Field Application and System Integration Notes
Redundancy Allocation and Slot Rules
The 3500 chassis features two half-height slots specifically engineered for power management on its left side.
- Redundant Operation: You can install two 3500/15-04-00 modules simultaneously to achieve a redundant power infrastructure. In this architecture, the lower slot serves as the primary power provider, while the upper slot functions as the automatic backup.
- Hot-Swapping: If a backup supply is present and healthy, you can extract a faulted power supply module while the machinery monitoring rack remains fully active. This hot-swap procedure will not disrupt machinery protection logic or trip communication buses.
Companion Power Input Module (PIM) Requirements
The 3500/15-04-00 main processor module cannot function on its own. It relies on a companion Low Voltage DC Power Input Module (PIM) installed directly behind it in the rear of the rack to terminate the raw 24 V DC field wiring lines.
- Compatibility Warning: The current production line high-capacity and low-voltage DC power supply modules are not backward compatible with legacy Bently Nevada 3500 PIM components designed prior to the hardware revision upgrades (verify compatibility block numbers against the OEM installation manual if executing drop-in replacements for racks deployed before 2020).
