Description
Bently 3300/12-02-20-00
Technical Specifications
- Module Type: Power Supply Unit
- Part Number: 3300/12-02-20-00
- Input Voltage: Wide-range AC or DC (Typically 100-240 VAC or 125 VDC)
- Output Voltage: Regulated -24 Vdc and +5 Vdc
Functional Features
- Enhanced Reliability: Built with updated electronic components to ensure long-term stability in harsh industrial environments.
- Comprehensive Protection: Includes robust over-current, over-voltage, and thermal protection mechanisms.
- Seamless Compatibility: Fully interchangeable with older 3300/12-01 power supplies in existing rack frames.
Application Scenarios
Used as a direct replacement or new installation in 3300 racks supporting critical rotating machinery in oil & gas, power generation, and marine applications.
Performance Parameters
- Power Efficiency: High-efficiency switching topology
- Ripple and Noise: Extremely low output ripple for clean sensor excitation
- Operating Temperature: -30°C to +65°C
Material Composition
Industrial-grade switching components, conformal-coated printed circuit boards, and a metallic shielded enclosure.
Structural Characteristics
Standard 3300 series form factor with front-panel status LEDs, ventilation slots, and rear plug-in backplane connectors.
Working Principle
Utilizes an isolated switch-mode power supply topology to step down and rectify incoming power, delivering precise DC voltages to the rack backplane.
Installation Requirements
Insert the module into the designated power supply slot in the 3300 rack. Ensure the rear connector is fully seated and tighten the front panel captive screws.
Usage Precautions
Verify input voltage matches the module’s rating before energizing. Never attempt to open or repair the power supply module internally. If the fault LED illuminates, systematically isolate backplane modules to identify the short circuit.
