The Bently Nevada 3500/15 AC and DC Power Supply Modules are critical 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, with any combination of AC and DC units.
One of the key advantages of this system is redundancy—if two power supplies are installed, the lower slot acts as the primary supply, while the upper slot serves as a backup. This ensures uninterrupted operation even if one module fails or is removed for maintenance.
Key Features of the 3500/15 Power Supply
The 3500/15 AC and DC Power Supplies are designed to handle a wide range of input voltages and convert them into stable power for other modules in the 3500 system. Key features include:
Universal Input Voltage Compatibility – Works with a broad range of AC and DC inputs.
Redundant Power Configuration – Dual power supplies ensure continuous operation.
Hot-Swappable Design – Modules can be replaced without shutting down the system (if a backup supply is present).
Flexible Installation – Supports mixed AC/DC configurations in the same rack.
Available Power Supply Options
The 3500 Series offers three main power supply options:
Universal AC Power Supply
Input Voltage: 110–220 Vac (nominal)
Non-hazardous areas: 85–264 Vac RMS
Hazardous areas: 85–250 Vac RMS
Peak Voltage: 120–373 Vac pk
Frequency: 47–63 Hz
High Voltage DC Power Supply
Designed for industrial environments requiring DC power input.
Low Voltage DC Power Supply
Suitable for systems with lower voltage DC requirements.
Installation and Redundancy Benefits
The 3500/15 Power Supply Modules are designed for easy installation and maintenance:
Primary & Backup Configuration: If two modules are installed, the lower slot is primary, and the upper is backup.
Hot-Swappable Operation: Removing or inserting a module does not disrupt system performance if a backup is active.
Wide Voltage Range: Ensures compatibility with various power sources globally.
This redundancy is crucial for industries where uninterrupted machinery monitoring is essential, such as oil & gas, power generation, and manufacturing.
Applications of the 3500/15 Power Supply
The Bently Nevada 3500/15 is widely used in industries requiring high reliability and continuous operation, including:
Oil & Gas – Protects turbines, compressors, and pumps.
Power Generation – Ensures stable operation of critical machinery.
Industrial Manufacturing – Maintains uptime for production equipment.
Chemical Plants – Provides safe power in hazardous environments.
Conclusion
The Bently Nevada 3500/15 AC Power Supply Module is a versatile and reliable solution for machinery protection systems. Its wide input voltage range, redundancy features, and hot-swappable design make it ideal for industries that demand uninterrupted power and system stability.
