• Diagnostic Fault Log: 500-event log with voltage/current data for post-event analysis.

• Gold-Plated Captive Washer Terminals: Corrosion-resistant and vibration-proof connections.

• Hot-Swappable: No rack power-down for replacement.

• Direct Retrofit: Replaces VPWRH1A and older power supply modules.

Application Fields

• Turbine Control Racks: Primary power source for Mark VIe racks in harsh environments

• Marine Applications: High-vibration engine room installations

• Offshore Platforms: Salt-spray and condensing environments

• Compressor Stations: High-vibration and chemical exposure environments

• Arctic/Desert Installations: Extreme temperature environments

• Retrofit Projects: Replaces older power supply modules in demanding applications

Comparison with LVPSG1A and Competitors

The GE IS2020RKPSG1A offers identical capacity to the LVPSG1A but with ruggedized construction, enhanced surge suppression, and silicone coating—making it the ideal power supply solution for harsh, high-vibration, and condensing environments.

Selection Guidelines

• When to choose:

  • High-vibration applications (marine, compressor stations, turbine decks)

  • Harsh environments (condensing, salt spray, chemical exposure, extreme temps)

  • Lightning-prone installations requiring enhanced surge suppression

• When to choose LVPSG1A instead: For standard environments with lower vibration and non-condensing conditions.

• Load Calculation: Sum all board loads—ensure total ≤200 W. +5 V rail ≤25 A; +3.3 V rail ≤20 A.

• Redundancy Planning: For critical turbines, order two GE IS2020RKPSG1A units with diode-OR configuration.

• Input Wiring: Use 12 AWG minimum; install fast-acting fuse (25 A) or circuit breaker.

• Cooling: Ensure cabinet airflow ≥150 LFM; derate above 65 °C.

• Coating Verification: Inspect under UV (365 nm)—silicone coating shows distinct fluorescence; verify edge encapsulation bead is continuous.

• Compatibility: Fits all Mark VIe VME64x racks. Requires ControlST v6.5 or higher.

Operational Precautions

1. Input Polarity: Double-check DC input polarity before power-up.

2. Load Calculation: Verify total rack load ≤200 W. Overloading +5 V rail (25 A max) is a common error—measure current draw during commissioning.

3. Vibration Mounting: In high-vibration installations, verify cabinet and module mounting are properly secured to prevent connector stress.

4. Status Monitoring: Regularly check front-panel LEDs—if any rail LED is amber/red, investigate downstream load.

5. Redundancy Testing: For redundant configurations, perform manual failover tests during outages.

6. Fault Log: Access 500-event log via Toolbox ST for post-event analysis.

7. Coating Care: Use GE-approved silicone-safe cleaner; inspect annually under UV—rework voids with approved silicone coating per GE FSB-MKVIe-112.

8. Hot-Swap: Remove/insert slowly under power—processor auto-recognizes new module.

9. Spare Stock: Maintain 1 spare per 3–4 racks; “RKPSG1A” backward-compatible with LVPSG1A/VPWRH1A sockets.

10. Firmware Updates: Ensure the GE IS2020RKPSG1A is in “standby” mode during updates.

11. ESD: Handle by edges only with grounded wrist strap—coating does not protect connectors.

12. Storage: Anti-static bag with desiccant at –40 to +85 °C; rotate every 3 years for coating inspection.
