Overview
Powering an aircraft on the ground is non-negotiable—avionics, cabin lights, galleys and maintenance laptops all depend on clean, stable electricity the moment the APU spins down. RH Aero’s Ground Power Units (GPUs), supplied through our global distribution partnerships, cover both diesel-driven and solid-state models. Each unit couples a rugged, apron-proof enclosure with an intuitive hybrid user interface that keeps life-cycle costs to a minimum.
Use Cases
Supported aircraft types
- Narrow-body jets (Airbus A320 Family, Boeing 737 Series)
- Wide-body jets (Airbus A330/A350, Boeing 777/787)
- Regional aircraft & turboprops (ATR 72, Embraer E-Jets)
- Business jets & helicopters — essentially “any type of aircraft” that requires 400 Hz AC or 28 V DC on the ground
Typical power-supply scenarios
- Turn-around servicing while the APU is off
- Overnight maintenance and software uploads in the hangar
- Remote stands or airports with limited fixed electrical infrastructure
- Cabin cleaning, catering, and environmental-control runs without burning jet fuel
Benefits
Dual technology line-up: Choose diesel-driven GPUs for off-grid flexibility or solid-state GPUs for zero-emission, low-noise hangar work.
Intuitive hybrid interface: Push-button + touch display lets ground crews start, stop and troubleshoot in seconds—even with gloves on.
Robust apron-grade build: Recyclable PC-UV panels, stainless and powder-coated steel shrug off UV, de-icing fluid and belt-loader bumps.
Lowest life-cycle cost: High-efficiency inverter tech plus plug-and-play electrical architecture cut fuel burn, service hours and spare-part spend.
Why RH Aero
When the wheels chock and the APU winds down, the GPU becomes the single engergy source of the aircraft. With RH Aero you get a access to power sources that're built to survive the harshest ramp climates, and supported by our worldwide service network. From quick gate turns to all-night avionics upgrades, RH Aero Ground Power Units deliver the reliable energy that keep your operation on schedule and on budget.
