Description
Bently 3500/15-05-05-CN
Technical Specifications
- Module Type: Dual Universal AC Power Supply
- Upper Slot Input: Universal AC Voltage (85 to 264 Vac RMS)
- Lower Slot Input: Universal AC Voltage (85 to 264 Vac RMS)
- Input Frequency: 47 to 63 Hz
- Regional Compliance: CN Standard Certification
Functional Features
- True N+1 Redundancy: Both power supplies can independently power the entire rack. If the primary (lower) supply fails, the secondary (upper) supply takes over instantly without interrupting rack operation.
- Universal Voltage Compatibility: Accepts a wide range of global AC voltages, eliminating the need for manual voltage selection switches.
- Hot-Swappable: Either power module can be removed or inserted while the system is energized, provided the second power supply is installed and functioning.
- Self-Monitoring: Features an internal self-supervision function that continuously verifies output voltage is within standard limits.
Application Scenarios
Extensively deployed in Chinese power generation plants, petrochemical complexes, metallurgical facilities, and large-scale manufacturing centers requiring CN-certified rotating machinery protection systems.
Performance Parameters
- Operating Temperature Range: -30°C to +65°C (-22°F to +150°F)
- Storage Temperature Range: -40°C to +85°C (-40°F to +185°F)
- Humidity Tolerance: Up to 95% non-condensing
- Output Status: Front-panel “Power OK” LED illuminates when output is nominal
Material Composition
Housed in a rugged, shielded metallic enclosure with industrial-grade internal switching power supply circuitry, high-capacity filtering capacitors, and premium line noise filters.
Structural Characteristics
Comprises two half-height modules that must be installed in the designated leftmost slots of the 3500 rack. The lower slot acts as the primary power source, while the upper slot serves as the redundant backup. Includes front-panel status LEDs and rear power input terminals.
Working Principle
Utilizes advanced switch-mode power supply technology to convert a wide range of AC input voltages into the precise, regulated DC voltages required by all 3500 monitoring modules. The redundant architecture ensures seamless power transfer during primary supply failure.
Installation Requirements
Must be installed in the leftmost special slots of the 3500/05 rack. Connect the Universal AC inputs using properly rated industrial conductors. Ensure the system is properly grounded using the single-point grounding provisions on the Power Input Module (PIM).
Usage Precautions
Verify that the input voltage falls within the 85 to 264 Vac RMS range. Never operate the system with only one power supply installed if redundancy is required for safety. Always observe electrical safety warnings and allow internal components to cool before handling.
