The Bently Nevada 3500/15 AC and DC Power Supplies are essential components in the 3500 Series Machinery Protection System. These half-height modules must be installed in designated slots on the left side of the rack. A single rack can accommodate one or two power supplies in any combination of AC and DC, with either supply capable of powering the entire rack independently.

Primary and Backup Power Supply Configuration
When two power supplies are installed, the module in the lower slot functions as the primary supply, while the one in the upper slot serves as the backup. This redundancy ensures continuous operation—if the primary supply fails, the backup takes over seamlessly. Additionally, removing or inserting either module does not disrupt the system as long as a second power supply remains operational.

Wide Input Voltage Range and Compatibility
The 3500/15 power supplies are designed to accept a broad range of input voltages, converting them to stable outputs suitable for other 3500 series modules. This flexibility makes them ideal for various industrial applications where power conditions may vary.

Available Power Supply Options
Bently Nevada offers three types of 3500/15 power supplies to meet different operational needs:

Universal AC Power Supply – Suitable for standard AC power sources.

High Voltage DC Power Supply – Designed for higher DC voltage inputs.

Low Voltage DC Power Supply – Optimized for lower DC voltage requirements.

Benefits of Using Redundant Power Supplies
Installing dual power supplies enhances system reliability by:

Preventing downtime during power supply failures.

Allowing hot-swapping of modules without system interruption.

Supporting continuous monitoring and protection of critical machinery.

Conclusion
The Bently Nevada 3500/15 AC and DC Power Supplies provide a robust and flexible power solution for machinery protection systems. With options for redundancy, wide voltage compatibility, and multiple power supply types, these modules ensure uninterrupted operation in industrial environments. Whether using AC or DC inputs, the 3500/15 power supplies deliver the reliability needed to keep critical systems running smoothly.
