Description
Bently Nevada 3500/15-02-02-01
Technical Specifications:
- Input Voltage: 175 to 264 Vac rms (high-voltage AC)
- Input Frequency: 47 to 63 Hz
- Output: Regulated DC voltages for rack modules (+8.5V, +21V, -31V and other rails as required)
- Module Type: Half-height
- Power Consumption: Typical rack load dependent
- 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: 95% non-condensing
- Dimensions: 120.7 × 50.8 × 251.5 mm
- Weight: 1.39 kg
Functional Features:
- Accepts high-voltage AC input and converts to regulated DC for all rack modules
- Supports hot-swap replacement when a second power supply is installed — removing or inserting either power module does not interrupt rack operation
- Redundant operation: when two power supplies are installed, the lower slot serves as primary and the upper slot serves as backup
- LED status indicator on the front panel shows power supply health (“Supply OK”)
- Built-in line noise filtering as standard
- Self-monitoring capability to verify output voltage is within specification
Application Scenarios:
- Power generation TSI systems requiring reliable AC-powered monitoring
- Petrochemical and refining machinery protection systems
- Any 3500 system installation where high-voltage AC mains power is available
- Redundant power configurations for critical machinery protection
Performance Parameters:
- Input voltage range: 175 to 264 Vac rms
- Input frequency: 47 to 63 Hz
- Conversion efficiency: high-efficiency design
- Output regulation: maintains stable DC rails under full rack load
- Hot-swap capability: full rack operation maintained during power supply replacement when redundant supply is installed
Material Composition:
- Industrial-grade electronic components on multi-layer PCB
- Metal enclosure with conformal coating on internal circuitry
- Gold-plated backplane edge connectors
Structural Features:
- Half-height module form factor
- Rear-loading plug-in design for 3500 rack
- Front panel LED status indicator
- Two half-height slots in the leftmost rack positions accommodate one or two power supplies
Working Principle:
The power supply module receives AC mains voltage through its input circuitry, applies line noise filtering, rectifies and regulates the voltage through an internal switching power supply circuit, and outputs multiple regulated DC voltage rails to the rack backplane. These DC rails power all installed monitor modules, relay modules, communication modules, and the Rack Interface Module.
Installation Requirements:
- Install in the leftmost designated power supply slot of the 3500 rack
- For redundant configuration, install a second 3500/15 module in the adjacent slot (upper or lower)
- Connect AC input wiring to the rear terminal block
- Ensure proper grounding of the rack and power supply
- Verify input voltage matches the module’s rated input range before energizing
