Description
Bently 3500/15-07-07-00
Technical Specifications
- Upper Slot Configuration: 07 (Low Voltage DC, 20-30 Vdc)
- Lower Slot Configuration: 07 (Low Voltage DC, 20-30 Vdc)
- Agency Approvals: 00 (None)
- Input Voltage: 20 to 30 Vdc for both modules
Functional Features
- True Redundancy: Either power supply can independently carry the full rack load. If the primary (lower) fails, the secondary (upper) seamlessly takes over.
- Hot-Swappable Maintenance: Failed power supplies can be replaced without powering down the rack or interrupting machinery monitoring.
- Load Sharing: Both modules operate in parallel to share the load, reducing thermal stress and extending component lifespan.
Application Scenarios
Mandatory for critical machinery protection systems, such as main steam turbines, large compressors, and emergency shutdown systems where zero downtime is required.
Performance Parameters
- Operating Temperature: -30°C to +65°C
- Storage Temperature: -40°C to +85°C
- Humidity: 95% non-condensing
- Maximum Input Current: 10.0 A per module
Material Composition
High-reliability industrial components, redundant internal circuitry, and robust mechanical connectors rated for thousands of insertion cycles.
Structural Characteristics
Occupies both left-side half-height slots. The lower module acts as the primary power source, while the upper module acts as the automatic backup.
Working Principle
The lower module powers the rack under normal conditions. The upper module remains active and synchronized. Upon detection of a primary fault, the upper module instantly assumes the full load without any voltage drop or system reset.
Installation Requirements
Install both modules in the left-side slots. Ensure both Power Input Modules (PIMs) have their single-point ground switches set to the exact same position (either both OPEN or both CLOSED).
Usage Notes
Always use identical power supply models for redundancy. Do not mix different voltage types (e.g., Low Voltage DC with High Voltage DC) in a redundant pair unless explicitly supported by the specific hardware revision.
