Bently 3500/15 106M1079-01-Y
Introduction
Bently Nevada, part of Baker Hughes, 3500/15 half-height universal AC power module for the 3500 machinery protection and condition-monitoring rack. It converts AC mains into regulated DC rails for monitoring, communication, and I/O modules. The -Y suffix in public distributor data indicates a configuration, certification, conformal-coating, or packaging variant; confirm the exact suffix meaning from the nameplate and purchase order.
Detailed content
Technical Specifications
Manufacturer: Bently Nevada, Baker Hughes
Model series: 3500/15
Part number: 106M1079-01-Y
Input voltage: public sources list 85 to 264 VAC rms universal and, for some -Y descriptions, 110 to 220 VAC nominal; verify nameplate
Input frequency: 47 Hz to 63 Hz in detailed distributor data
Output: regulated rack DC rails; detailed third-party data lists +5 V, +15 V, -15 V and 150 W continuous, while standard Bently summaries emphasize universal AC and half-height rack power
Dimensions: 120.7 mm x 50.8 mm x 251.5 mm
Weight: 1.39 kg
Operating temperature: -30°C to +65°C in standard-summary data; -40°C to +70°C in extended third-party data
Storage temperature: -40°C to +85°C
Redundancy: supports dual power supply configuration
Hot swap: supported only when a second qualified power module is installed and active
Compliance in public data: EN50081-2, EN55011, CSA/NRTL/C, Class 1 Div 2 Groups A-D depending on variant
Function Features
Wide-range AC input, half-height rack format, front-panel status LEDs, fault relay reporting in detailed data, overvoltage and overcurrent protection in detailed data, and redundant power support for continuous machinery monitoring.
Material Composition
Metal sheet-metal enclosure in detailed distributor data, internal power semiconductors, EMI filtering components, electrolytic and film capacitors, and rack edge connectors.
Structure
3500-series plug-in module with front AC terminal access and status indicators in some variants, rear backplane edge connection, and designated left-side power-slot installation in standard rack descriptions.
Working Principle
AC mains passes EMI filtering, rectification, and power conversion; internal regulation produces the DC rails required by the 3500 backplane. Supervision circuits monitor output voltage, current, and temperature, then report faults through LEDs and relay contacts.
Application Scenarios
Turbine vibration monitoring, compressor protection, pump and motor condition monitoring, power-generation turbine supervisory systems, petrochemical rotating-equipment protection, and any 3500 rack requiring redundant or maintainable AC power.
Installation Requirements
Install in the designated 3500 power slot and confirm left-side placement rules from the rack manual. Verify AC source voltage and frequency before connection. Ground the rack properly. Leave ventilation clearance for the module. Tighten AC terminals to specification.
Usage Notes
Verify the -Y suffix against required agency certification, coating, or regional configuration. Do not run single-power configurations as hot-swappable. If the green LED is absent or red, check AC input, seating, backplane, and output loading. Calculate total rack power before adding modules.
