Description
Bently 3300/12-02-22-00
Technical Specifications
- Product Series: 3300 Series Machinery Protection System
- Part Number: 3300/12-02-22-00
- Input Voltage: 115 VAC or 220 VAC
- Output: Regulated DC voltages for 3300 monitoring modules and transducers
- Capacity: Powers up to 12 modules and associated transducers
Functional Features
- Integrated Line Filtering: Features built-in line noise filtering to ensure stable operation and clean power delivery even in electrically noisy industrial environments.
- Single-Slot Efficiency: Eliminates the need for a second power supply in the same rack, simplifying system installation, wiring, and maintenance.
- Harsh Environment Protection: The internal circuit board is treated with a conformal coating to provide enhanced protection against dust, moisture, and corrosive contaminants.
Application Scenarios
Widely deployed in power generation, petrochemical, oil and gas, and heavy manufacturing facilities to provide uninterrupted power to critical rotating machinery protection systems, including turbines, compressors, and pumps.
Performance Parameters
- Operating Temperature: Standard industrial operating range (-30°C to +65°C)
- Power Conversion Efficiency: High-efficiency switching topology with low output ripple
- Protection Mechanisms: Integrated over-voltage, short-circuit, and thermal protection
Material Composition
Industrial-grade electronic switching components, high-dielectric conformal coating, and a ruggedized metallic shielding enclosure.
Structural Characteristics
Standard 3300 series form factor featuring front-panel status LEDs, ventilation slots for thermal management, and a rear plug-in backplane connector. Dimensions are optimized for standard rack mounting.
Working Principle
Operates as an isolated switch-mode power supply, stepping down and rectifying incoming AC power to deliver precise, stable DC voltages to the 3300 rack backplane for sensor excitation and logic processing.
Installation Requirements
Must be installed exclusively in Slot 1, the left-most position in the 3300 rack. Ensure the rear backplane connector is fully seated and secure the front panel captive screws.
Usage Precautions
Verify the 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 potential short circuits.
