Description
BENTLY NEVADA 3500/15 AC/DC Power Supply Module
1. Product Description
The BENTLY NEVADA 3500/15 is a half-height power supply module designed for the 3500 Machinery Monitoring System. It accepts a wide range of AC (85–264 VAC) and DC (20–30 VDC or 88–140 VDC) input voltages and converts them into stable 24 VDC power for other 3500 modules. With redundant power support and hot-swap capabilities, the 3500/15 ensures continuous operation in critical applications, such as rotating machinery monitoring in oil & gas, power generation, and manufacturing. Its compact design and compatibility with legacy systems make it ideal for retrofits and new installations.

3. Advantages and Features
- Dual Power Redundancy: Two power supplies (AC/DC mix) can be installed, with one acting as a backup to ensure uninterrupted operation.
- Wide Input Range: Adaptable to global voltage standards, reducing the need for external voltage converters.
- Hot-Swap Capability: Modules can be replaced without disrupting rack operation when redundancy is enabled.
- Built-in Protection: Overvoltage, overcurrent, and short-circuit protection safeguard connected equipment.
- Self-Test Function: Monitors output stability and alerts users to deviations.
Case Study: A refinery reduced downtime by 30% using the 3500/15’s redundant power design to maintain continuous vibration monitoring during power supply maintenance.
4. Application Fields and Case Studies
Industries:
- Oil & gas, power generation, petrochemicals, and manufacturing.
典型应用:
- Turbines, compressors, pumps, and other rotating equipment requiring reliable power for condition monitoring.
Case Study: A power plant achieved 99.9% uptime by integrating the 3500/15 with its generator monitoring system, ensuring stable power during grid fluctuations.
5. Competitive Comparison
The BENTLY NEVADA 3500/15 stands out through:
- Universal Voltage Compatibility: Supports both AC and DC inputs, unlike many single-voltage alternatives.

6. Selection Recommendations
- Input Type: Choose AC or DC versions based on site power availability.
- Redundancy Needs: Opt for dual modules in safety-critical applications.
- Environmental Conditions: Ensure the module’s -30°C to +65°C temperature range matches the installation environment.
7. Precautions
- Installation: Install in designated left-side rack slots and avoid mixing legacy and new Power Input Modules (PIMs).
- Grounding: Properly ground the rack chassis to prevent electrostatic discharge and electrical hazards.
- Maintenance: Regularly inspect power connections and update firmware for optimal performance.
