1. Core Specifications

• ‌Official Part Number‌: 114M5330-01
• ‌Product Family‌: 3500/15 Power Module Series
• ‌Manufacturer‌: Bently Nevada (Baker Hughes)
• ‌Physical Form Factor‌: Half-height module, occupying only one dedicated power slot on the far left of the 3500 rack
• ‌Net Weight‌: 0.4 kg (0.88 lb)

• ‌Country of Origin‌: United States
• ‌Standard Warranty‌: 12 months for brand new original units

2. Key Technical Parameters

• ‌Input Voltage Range‌: 20–30 VDC, perfectly matching the 24 VDC power supply standard widely adopted in industrial sites
• ‌Stabilized Output‌: 24 VDC, fully compatible with the power demand of all modules in the 3500 system
• ‌Maximum Output Current‌: 11.0 A, capable of supporting a fully populated 3500 rack under full load conditions
• ‌Operating Temperature‌: -30°C to +65°C (-22°F to +150°F)
• ‌Storage Temperature‌: -40°C to +85°C (-40°F to +185°F)
• ‌Humidity Tolerance‌: 95% non-condensing, adapting to high-humidity industrial environments
• ‌No Minimum Rack Load Requirement‌: The module can operate stably even when the 3500 rack is not fully configured with monitoring cards

3. Distinctive Features

• ‌Redundancy Compatibility‌: A single 3500 rack can install 1 or 2 units of this module. Under dual-module configuration, the two units share the load automatically, and the backup unit will take over seamlessly once the primary power supply fails
• ‌Hot-Swap Capability‌: Under redundant operation, the module can be inserted or removed directly without shutting down the entire 3500 system, enabling zero-downtime maintenance and replacement
• ‌Built-In Self-Monitoring & Diagnostics‌: The module continuously verifies that its output voltage stays within the specified range. The front-panel «Supply OK» LED provides instant visual confirmation of normal operation
• ‌Rugged Industrial Design‌: Manufactured to Bently Nevada’s strict reliability standards, it can withstand the harsh vibration, electromagnetic interference and temperature fluctuations common in heavy industrial sites
• ‌Integrated Protection Mechanisms‌: Equipped with built-in overload, short-circuit and over-temperature protection, it automatically triggers protection actions under abnormal conditions to avoid damaging other precision monitoring modules in the rack

4. Installation Guidelines

• ‌Pre-Installation Preparation‌: Confirm the 3500 rack is properly grounded, verify the field 24 VDC power supply matches the module’s voltage rating and correct polarity, and power off the entire rack before handling the unit
• ‌Mounting Steps‌: Align the module with the dedicated power slot on the far left of the 3500 rack, slide it in slowly, and ensure the rear backplane connector is fully and securely mated
• ‌Wiring Operation‌: Connect the field DC power cables to the module’s internal terminals strictly following the positive and negative polarity marks
• ‌Redundancy Setup‌: If dual power supply configuration is required, install the second 114M5330-01 module in the adjacent dedicated power slot
• ‌Post-Installation Verification‌: Restore the main power supply, confirm the front-panel «Supply OK» LED illuminates normally, and check that all other modules in the 3500 rack power up and enter normal operation status

5. Maintenance & Troubleshooting

• ‌Routine Maintenance‌: No frequent disassembly or internal calibration is required. Periodically check that the module is securely seated in the rack, the power wiring terminals remain tight, and the unit is free of excessive dust buildup that may block heat dissipation
• ‌Fault Diagnosis‌: If the status LED turns off or the 3500 system reports a power loss alarm, first confirm the field 24 VDC input power is normal, then check if the module backplane connector has loosened. For persistent failures, contact authorized Bently Nevada service personnel for professional inspection
• ‌Safety Reminder‌: Always disconnect the main power of the entire 3500 system before performing any maintenance, wiring or replacement operations on the module
