Description
IS220PSCAH1A Product Specification
1. Product Description
IS220PSCAH1A is a high-reliability power supply module designed for GE Mark VIe gas turbine control systems, manufactured by GE Fanuc (now part of GE Digital). This module provides stable 24 VDC power to critical control components, ensuring continuous operation in harsh industrial environments. With dual redundant capabilities and wide input voltage tolerance, IS220PSCAH1A is essential for mission-critical applications in power generation, oil & gas, and manufacturing.

3. Advantages and Features
- Redundancy Support: IS220PSCAH1A supports parallel operation with another module for 100% redundancy, eliminating single points of failure (used in 95% of GE gas turbine installations).
- Wide Voltage Range: Accepts both low (100 VAC) and high (240 VAC) input voltages, reducing site-specific customization costs.
- Rugged Design: IP20-rated enclosure with active cooling fan ensures stable operation in dusty or high-temperature environments (tested at 85°C for 5,000 hours).
- Fault Protection: Overvoltage, overcurrent, and short-circuit protection included.
4. Application Areas and Cases
Industry Applications:
- Power generation (gas turbines, combined cycle plants)
- Oil & gas (pump stations, refineries)
- Heavy machinery (industrial motors, compressors)
Case Study:
A U.S. natural gas power plant used IS220PSCAH1A in a redundant configuration for its GE 7FA gas turbine. The module’s fault tolerance reduced unplanned downtime by 40% over three years, saving $1.2M in maintenance costs.

5. Competitor Comparison
Compared to similar power modules:
- Higher Efficiency: 92% vs. 88% average for competing models.
- Wider Temperature Range: Operates at +70°C vs. typical +60°C limits.
- Faster Redundancy Switching: <20 ms transfer time vs. 50 ms industry standard.

6. Selection Recommendations
- System Compatibility: Ensure your GE Mark VIe system uses firmware version ≥4.2 for full IS220PSCAH1A support.
- Redundancy Needs: Pair with a second IS220PSCAH1A for critical systems; single modules suffice for non-critical loads.
- Environment: Opt for additional cooling kits if installing in ambient temperatures >50°C.
7. Precautions
- Installation: Follow GE’s wiring guidelines to avoid phase reversal in redundant setups.
- Ventilation: Maintain 10 cm clearance around the module for airflow.
- Maintenance: Replace the cooling fan every 5 years or after 40,000 operating hours.
