1. Core Specifications

• ‌Part Number‌: 133300-01
• ‌Manufacturer‌: Bently Nevada (Baker Hughes)
• ‌Product Category‌: Low Voltage DC Power Input Module
• ‌Series Compatibility‌: 3500/15 power module family, fully integrated with the 3500 system platform
• ‌Physical Dimensions‌: 120.7 mm × 25.4 mm × 114.3 mm (4.75 in × 1.0 in × 4.5 in)
• ‌Net Weight‌: 0.34 kg (0.75 lb)
• ‌Country of Origin‌: United States
• ‌Warranty Coverage‌: 12 months for brand new original units

2. Key Electrical Parameters

• ‌Input Voltage Range‌: 20–30 VDC (low voltage DC input)
• ‌Stabilized Output‌: Converts raw DC input to the standardized +24 VDC required by the 3500 system
• ‌Maximum Output Current‌: Up to 5.2 A, sufficient to power a fully populated 3500 rack independently
• ‌Operating Temperature‌: -30°C to +65°C (-22°F to +150°F)
• ‌Storage Temperature‌: -40°C to +85°C (-40°F to +185°F)
• ‌Relative Humidity Tolerance‌: 95% non-condensing, suitable for harsh industrial environments

3. Distinctive Features

• ‌Redundancy Support‌: A single 3500 rack can accommodate 1 or 2 power modules in any AC/DC combination, with the lower slot unit acting as primary and the upper as automatic backup
• ‌Hot-Swap Capability‌: Under redundant configuration, the module can be inserted or removed without interrupting the entire system operation
• ‌Compact Half-Height Design‌: Occupies minimal rack space, leaving more slots available for monitoring and I/O modules
• ‌Built-In LED Status Indicator‌: Front-panel LED clearly displays real-time power supply health for quick on-site status verification
• ‌Internal Terminal Block‌: Simplifies field DC power wiring and reduces connection errors during installation
• ‌Wide Input Compatibility‌: Tolerates typical industrial DC voltage fluctuations without triggering unexpected shutdowns

4. Installation Guidelines

• ‌Pre-Installation Preparation‌: Confirm the 3500 rack is properly grounded, verify the field DC power supply matches the module’s voltage rating and polarity, and power off the rack before handling the unit
• ‌Mounting Steps‌: Carefully slide the module into the dedicated power slot on the far left of the 3500 rack, ensure the rear connector fully mates with the backplane, then connect the field DC power cables to the internal terminals following correct polarity
• ‌Redundancy Setup‌: If dual power supply configuration is required, install the second 133300-01 module in the adjacent dedicated power slot
• ‌Post-Installation Check‌: Restore power and confirm the front-panel LED illuminates normally, verify all other modules in the rack power up and operate as expected

5. Maintenance & Troubleshooting

• ‌Routine Maintenance‌: No frequent disassembly or internal calibration is required. Periodically check that the module is securely seated in the rack, power wiring remains tight, and the unit is free of excessive dust buildup that could block heat dissipation
• ‌Fault Diagnosis‌: If the status LED turns off or the system reports power loss, first confirm the field DC 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 3500 system main power before performing any maintenance or wiring operations on the module

6. Compatible Same-Series Models
