Key Features & Benefits
1. Pristine Power Output
Pure Sine Wave Technology: Utilizes cutting-edge IGBT (Insulated Gate Bipolar Transistor) technology to generate a truly pure sine wave output.
Tightly Regulated Voltage & Frequency: Maintains ultra-stable 115/200V AC (or other specified voltages) and 400Hz frequency, crucial for sensitive aircraft avionics.
Ultra-Low Harmonic Distortion (THD): Ensures minimal interference (typically <2% THD) to safeguard delicate aircraft electronic systems and extend equipment lifespan.
Rapid Transient Response: Quickly adapts to sudden load changes, preventing power fluctuations that can impact aircraft systems.
2. Exceptional Energy Efficiency & Cost Savings
High Power Factor: Operates with a power factor exceeding 0.95, minimizing reactive power and reducing utility bills.
Superior Efficiency (>90%): Converts input power to output with minimal losses, significantly reducing energy consumption compared to rotary converters.
Low No-Load Consumption: Consumes very little power when not actively supplying an aircraft, contributing to further savings.
Reduced Operational Costs: Lower electricity bills, decreased maintenance, and eliminated fuel costs translate into substantial long-term savings and a rapid return on investment (ROI).
3. Superior Reliability & Low Maintenance
Solid-State Design: No moving parts, clutches, or belts to wear out, significantly enhancing reliability and extending service life.
Robust Industrial-Grade Components: Built with high-quality, durable components designed for continuous duty and harsh operating environments.
Maximized Uptime: Eliminates common failure points of mechanical systems, leading to fewer breakdowns and increased aircraft availability.
Reduced Scheduled Maintenance: Requires minimal preventative maintenance, lowering labor costs and spare parts inventory.
4. Quiet & Environmentally Friendly Operation
Whisper-Quiet Operation: Operates at very low noise levels (typically <65 dB(A) at 1 meter), improving the working environment for ground crews and reducing noise pollution in sensitive areas.
Zero Direct Emissions: Produces no exhaust gases, contributing to cleaner air quality around the apron and supporting environmental sustainability initiatives.
Reduced Carbon Footprint: Directly contributes to a lower carbon footprint for airport operations, aligning with global environmental standards.
5. User-Friendly Interface & Diagnostics
Intuitive Touchscreen Display: Features a clear, multi-language color touchscreen for easy operation, monitoring, and configuration.
Real-time Operational Data: Provides instant access to critical parameters such as voltage, current, frequency, power factor, and load status.
Comprehensive Diagnostics: Built-in self-diagnostics, fault logging, and alarm indicators enable quick troubleshooting and proactive maintenance.
Remote Monitoring (Optional): Can be integrated into airport control systems for centralized monitoring and management.
6. Robust & Durable Construction
Weather-Resistant Enclosure: Available with IP54 or IP55 rated enclosures, providing excellent protection against dust, water spray, and extreme weather conditions.
Corrosion-Resistant Materials: Constructed from high-quality, corrosion-resistant metals and finishes for long-lasting performance in challenging outdoor environments.
Designed for Continuous Operation: Engineered to withstand the rigors of airport operations, from freezing winters to scorching summers.
7. Advanced Safety Features
Comprehensive Protection Circuits: Includes overload, over-voltage, under-voltage, over-frequency, under-frequency, short-circuit, and over-temperature protection.
Aircraft Interlock Safety: Integrated safety mechanisms ensure proper connection and disconnection procedures, safeguarding both the aircraft and ground personnel.
Emergency Stop Button: Easily accessible emergency stop for immediate power shutdown.
8. Customization & Scalability
Flexible Power Ratings: Available in a range of standard kVA ratings (e.g., 90 kVA, 120 kVA, 180 kVA) to suit various aircraft types and operational needs.
Versatile Configurations: Offered in mobile, fixed (pedestal-mounted), bridge-mounted, or under-apron designs.
Optional 28V DC Output: Can be equipped with an integrated 28V DC output for smaller aircraft or specific maintenance tasks.
Typical Applications
Commercial Airports: Gate power for regional, narrow-body, and wide-body aircraft at passenger terminals and hard stands.
Maintenance, Repair & Overhaul (MRO) Facilities: Reliable power for hangar operations, testing, and servicing aircraft.
Military Airbases: Robust and dependable power for military aircraft and specialized ground support equipment.
Aircraft Manufacturing & Testing Facilities: Precision power for aircraft assembly lines and pre-delivery testing.
Corporate & Private Jet Terminals: High-quality, quiet power solutions for executive and private aircraft.
