In the aviation industry, reliability, efficiency, and safety are paramount. Every aircraft, whether on the ground preparing for takeoff or undergoing maintenance, requires a dependable source of power. This is where Ground Power Units (GPUs) play an essential role. Among the various power capacities available, the GPU 90 KVA has emerged as one of the most versatile and widely used models, bridging the gap between smaller portable units and higher-capacity systems.

If you’re an aviation professional, airport operator, or ground support service provider searching for the right solution, understanding the value of a GPU 90 KVA will help you make an informed decision. Let’s explore why this specific GPU configuration is a preferred choice, its applications, benefits, and what sets manufacturers like JTL apart in delivering high-performance ground power solutions.

What is a GPU 90 KVA?

A Ground Power Unit (GPU) is an external power supply system designed to deliver consistent and stable electrical power to aircraft while they are parked on the ground. Instead of relying on the aircraft’s Auxiliary Power Unit (APU), which consumes expensive aviation fuel and creates noise and emissions, GPUs supply power from an external source.

The GPU 90 KVA is an engine-driven or plug-in power solution with a capacity of 90 kilovolt-amperes (KVA). This rating makes it suitable for powering medium to large commercial aircraft, regional jets, and certain military planes. It ensures that all onboard systems, such as avionics, lighting, air conditioning, and communication devices, function seamlessly without draining the aircraft’s internal resources.

Why Choose a 90 KVA GPU?

When considering the right GPU size for your operations, capacity is crucial. The 90 KVA GPU hits the sweet spot for many aviation operators because:

  1. Balanced Power Output
     It provides enough power to handle the electrical needs of mid-size and even larger aircraft without being oversized or underpowered.

  2. Fuel Efficiency
     Compared to running an aircraft’s APU, the GPU 90 KVA consumes far less fuel, saving money in the long run.

  3. Reduced Emissions
     Modern 90 KVA GPUs meet or exceed environmental standards, helping airports comply with carbon reduction targets.

  4. Compatibility
     It can support both AC and DC power configurations, making it adaptable for various fleets.

  5. Proven Reliability
     Established manufacturers, such as those offering the JTL series since 2003, have refined the design for maximum reliability and operational efficiency.

Technical Highlights of a GPU 90 KVA

While specifications vary by manufacturer, a typical GPU 90 KVA comes with the following features:

  • Voltage Options: 28.5 VDC, 115/200 VAC (400 Hz), suitable for both narrow-body and wide-body aircraft.

  • Engine-Driven & Plug-In Models: Flexibility to choose between mobile diesel-driven units and fixed electric plug-in versions.

  • Durability: Rugged design built to withstand harsh airport environments.

  • User-Friendly Controls: Digital displays, monitoring systems, and protective mechanisms for safe operation.

  • Compliance with Standards: Meets or exceeds international aviation power standards (ISO, SAE, and IATA).

Applications of GPU 90 KVA

The GPU 90 KVA is widely deployed across airports, maintenance hangars, and military bases. Its applications include:

  • Commercial Aviation – Powering narrow-body aircraft such as Boeing 737s, Airbus A320s, and similar jets.

  • Military Aviation – Supporting tactical aircraft, cargo planes, and training jets.

  • Regional Airlines – Efficiently powering smaller fleets that require versatile and portable power solutions.

  • MRO Facilities – Providing dependable power during repair, testing, and maintenance of avionics systems.

By meeting these diverse needs, the GPU 90 KVA has become a preferred choice for ground operations worldwide.

Engine-Driven vs. Plug-In GPU 90 KVA

One of the advantages of the 90 KVA model is its availability in both engine-driven and plug-in variants.

  • Engine-Driven GPU 90 KVA

    • Mobile and flexible for ramp operations.

    • Powered by efficient diesel engines.

    • Ideal for airports with multiple gates or remote operations.

  • Plug-In GPU 90 KVA

    • Fixed installation, often mounted at gates or hangars.

    • Powered by the local electric grid.

    • Environmentally friendly with zero local emissions.

    • Reduced operating costs compared to fuel-driven models.

Choosing between the two depends on your operational environment and long-term cost considerations.

Benefits of Using a GPU 90 KVA

Switching to a 90 KVA Ground Power Unit offers numerous advantages, such as:

  1. Operational Cost Savings
     By reducing reliance on APUs, airports save significantly on fuel and maintenance expenses.

  2. Extended APU Life
     Frequent APU use leads to wear and expensive repairs. Using a GPU reduces operational hours and prolongs lifespan.

  3. Environmental Sustainability
     Many 90 KVA units meet international green airport initiatives by lowering noise and emissions.

  4. Improved Safety
     Built-in protective systems guard against over-voltage, under-voltage, and overload scenarios.

  5. Increased Aircraft Turnaround Efficiency
     Provides immediate and reliable power, streamlining the boarding, cleaning, and servicing processes.
