Key Features
- Redundant Architecture
- Dual independent power inputs with OR-ing diodes for seamless failover.
- Hot-Swap Capability
- Supports live insertion/removal without rack shutdown (requires compatible backplane).
- Intelligent Monitoring
- LED status indicators (Input OK, Output OK, Fault) + PMBus communication for voltage/current/temp telemetry.
- High Power Density
- 240W total output power in single-slot width (3U height).
- Active PFC (Power Factor Correction)
- Meets IEC 61000-3-2 harmonic standards (>0.95 PF).
Purpose & Functionality
- Primary Power Distribution: Supplies stable +5.1V logic power to Mark VIe controllers (e.g., IS200ERKG-).
- Auxiliary Power: Provides +24V for I/O modules, sensors, and relays.
- System Reliability: Redundant design prevents turbine trips during power source failures.
- Noise Immunity: Filtered outputs protect sensitive control electronics.
Applications & Industries
Deployed in critical power infrastructure requiring zero downtime:
- Energy Generation
- Gas/Steam Turbine Controls, Wind Farm Substations.
- Oil & Gas
- Offshore Platform Control Systems, LNG Compressor Stations.
- Industrial Automation
- High-availability PLC Racks, Safety Shutdown Systems (SIS).
- Transportation
- Locomotive Propulsion Controls, Maritime Power Management.
Integration Notes
⚠️ Critical Compatibility:
- Backplane: Requires Mark VIe JBPD/JBTA/JBRB-series racks.
- Parallel Operation: Max. 4 modules per rack (N+1 redundancy recommended).
- Cooling: Ensure ≥25 CFM airflow; derate output above 55°C ambient.
🔧 Maintenance Best Practices:
- Monitor fan health via ToolboxST™ software.
- Replace every 8–10 years (electrolytic capacitor aging).
Documentation & Ordering
- Manual: GEH-6850 (Mark VIe Systems Guide) / GEI-100869 (Power Supply Installation)
- Drawing: GDK-2305A (JPDD Wiring & Pinout)
- Replacement Kit: Includes mounting hardware, connectors (Order PN: IS200JPDDG4ABA).
⚠️ Warning: Use only GE-supplied power modules. Third-party units risk non-compliance with SIL 2/3 safety requirements.
