In the fast-paced world of aviation, reliability, efficiency, and performance are non-negotiable. Aircraft operations demand a constant supply of high-quality electrical power, both on the ground and in flight. Ground Power Units (GPUs) have become the backbone of modern ground support equipment, supplying the necessary power for aircraft systems while parked, boarding, or undergoing maintenance. Among the wide range of options available, the GPU 90 KVA has established itself as a versatile and indispensable solution for airports, airlines, and maintenance crews across the globe.
In this blog, we will dive deep into the GPU 90 KVA, its applications, benefits, technical specifications, and why choosing the right manufacturer makes all the difference in the aviation sector. Whether you are part of an airline, MRO (Maintenance, Repair, and Overhaul) facility, or airport operations, understanding the value of a 90 KVA Ground Power Unit can help optimize efficiency and ensure smooth, uninterrupted operations.
What is a GPU 90 KVA?
A GPU 90 KVA is a Ground Power Unit designed to deliver 90 kilovolt-amperes (KVA) of electrical power to aircraft while on the ground. Instead of running an aircraft’s auxiliary power unit (APU), which consumes jet fuel and produces emissions, GPUs supply external power directly from the ground. This not only saves fuel and reduces emissions but also prolongs the life of the aircraft’s onboard systems.
GPUs can be either:
- Engine-driven – powered by diesel engines, offering mobility and flexibility.
- Plug-in/electric – connected directly to the local grid for quieter and more eco-friendly operation.
The 90 KVA capacity makes this model ideal for medium to large aircraft, striking a balance between efficiency, compactness, and power delivery.
Why Choose a GPU 90 KVA?
When selecting a Ground Power Unit, the power rating is one of the most crucial factors. Here’s why the GPU 90 KVA stands out:
1. Optimal Power for Wide Applications
A 90 KVA GPU is capable of supporting a wide range of aircraft, including regional jets, narrow-body airliners (such as the Boeing 737 and Airbus A320), and some larger business jets. It provides sufficient power for running avionics, lighting, air conditioning, galley systems, and maintenance checks.
2. Fuel and Cost Savings
Instead of relying on expensive jet fuel to run an aircraft’s APU, airlines can save significantly by using a GPU. Over time, the operational cost savings make the GPU 90 KVA a smart investment.
3. Environmental Benefits
Plug-in models of the 90 KVA GPU run on electricity, drastically cutting down carbon emissions and noise pollution. Even engine-driven versions are optimized to meet international emission standards.
4. Durability and Reliability
Manufacturers who comply with published aviation standards design GPUs that can withstand demanding airport environments, from scorching heat to freezing conditions.
5. Scalability
For airports and MRO facilities, a GPU 90 KVA can integrate seamlessly into existing ground support fleets, offering scalable solutions for operations that handle multiple aircraft sizes.
Technical Features of GPU 90 KVA
While the specifications may vary by manufacturer, a typical 90 KVA GPU includes the following features:
- Output Power: 90 KVA (AC or DC configurations available depending on aircraft requirements).
- Voltage: Standard outputs like 28.5 VDC or 115/200 VAC, 400 Hz, compatible with industry requirements.
- Design: Compact, rugged, and mobile for airside usage.
- Cooling System: Advanced air or liquid cooling systems to ensure consistent performance.
- Safety Systems: Overload protection, ground fault detection, emergency shutdowns.
- User-Friendly Interface: Easy monitoring of voltage, frequency, and load parameters.
- Compliance: Meets or exceeds standards such as ISO, SAE, IATA, and other aviation regulations.
Engine-Driven vs. Plug-In GPU 90 KVA
Choosing between engine-driven and plug-in models depends on your operational environment:
- Engine-Driven GPU 90 KVA:
- Powered by diesel engines.
- Ideal for remote locations or areas without reliable grid power.
- Provides maximum mobility on the apron.
- Plug-In GPU 90 KVA:
- Connected to the local electrical grid.
- Environmentally friendly and quieter.
- Perfect for airports with green initiatives and stable power infrastructure.
Many manufacturers offer both types, with models designed under prefixes like JTL, ensuring versatility and compliance with global aviation needs.
