When your operation depends on keeping aircraft powered safely and efficiently on the ground, the choice of a Ground Power Unit (GPU) is critical. The Jetall 60 KVA ground power unit has become a trusted workhorse for airlines, MROs, FBOs, and military operators that need dependable 400 Hz AC power (and optional 28.5 VDC) with minimal downtime and predictable lifecycle costs. Since 2003, Jetall’s JTL-prefix models—available in both engine-driven and plug-in (utility-powered) configurations—have been designed to meet or exceed existing published standards, giving ramp teams the confidence to power today’s fleets with precision.
Why 60 KVA—and Why Jetall?
Sixty kVA is the sweet spot for many ramp scenarios. It comfortably supports a wide range of business jets and regional aircraft and can handle common single-aisle commercial types during normal turnarounds, cabin servicing, and avionics checks. For operators, this means one unit can cover more gate or hangar use cases, simplifying deployment and training.
What sets Jetall apart is a long track record of practical engineering. The company’s JTL series has been on the market for over two decades, continually refined with real-world feedback from line maintenance and ground handling teams. Whether you choose an engine-driven or a plug-in model, the Jetall 60 KVA ground power unit delivers stable output, smart protections, and easy service access in a rugged package built for the ramp.
Engine-Driven vs. Plug-In: Choose the Power Strategy That Fits
Engine-Driven (Mobile) JTL Models
- Go-anywhere versatility: Ideal for remote stands, flight-line maintenance, and ramp areas without reliable utility access.
- Fast response: Roll up, connect, and power the aircraft without waiting for facility power or cable runs.
- Optimized fuel efficiency: Modern engines are tuned for GPU duty cycles, helping reduce fuel burn and emissions during typical ground turns.
Plug-In (Utility-Powered) JTL Models
- Lower operating cost: When grid power is available, plug-in units minimize fuel use and reduce emissions.
- Quiet operation: Perfect for hangar work, avionics testing, and noise-sensitive environments.
- Consistent 60 KVA delivery: Clean, stable 400 Hz AC power with the option to add 28.5 VDC for mixed-fleet support.
Both families share Jetall’s common design language and controls, so technicians can switch between them with minimal retraining—another plus for busy operations.
Power You Can Trust: Electrical Performance That Protects the Aircraft
A great GPU does more than “turn on.” It must protect sensitive onboard systems from voltage droop, spikes, and frequency deviations. The Jetall 60 KVA ground power unit is engineered with tight regulation and fast transient response, keeping 400 Hz AC output stable during load inrushes from galley equipment, ECS starters, or avionics boot cycles. Over- and under-voltage protections, short-circuit safeguards, and thermal monitoring are built in to protect both the unit and the aircraft.
For operators that also need DC power—for example, battery top-off, avionics work on smaller aircraft, or mixed fleet support—Jetall’s heritage in 28.5 VDC systems ensures the same robust design philosophy applies across configurations.
Built for the Ramp: Durability, Serviceability, and Safety
Ramp environments are unforgiving. Jetall designs the JTL line to withstand vibration, weather, and constant movement:
- Ruggedized enclosures & frames: Powder-coated housings, protected louvers, and reinforced tow points help the unit survive years of daily use.
- Intuitive control panels: Clear readouts and status indicators reduce error risk and speed up handovers between shifts.
- Easy service access: Panels open quickly for filters, belts, and routine inspections; common spares and consumables keep maintenance simple.
- Safety-first features: Emergency stop, interlocks, cable strain relief, and guarded connectors help prevent incidents and damage.
Scalable by Design: From 38 KVA to 140 KVA
While this article focuses on the Jetall 60 KVA ground power unit, it sits in a broader Jetall lineup ranging from 38 kVA to 140 kVA AC models, alongside 28.5 VDC configurations. That means you can standardize on one vendor for diverse power needs—narrow-body gates, wide-body hangar bays, remote stands, and business jet operations—while keeping training and spares common across the fleet.
Real-World Advantages You’ll Notice on Day One
- Faster turns & fewer delays: Stable output and smart protections mean fewer nuisance trips and faster power-on sequences.
- Lower total cost of ownership: Proven platforms, accessible service points, and long component life help keep lifecycle costs predictable.
- Operator-friendly: Clear labeling, ergonomic cable management, and straightforward controls reduce training time and human error.
- Compliance-ready: Engineered to meet or exceed published industry standards and OEM ground power requirements, supporting audit-ready operations.
Typical Use Cases for a Jetall 60 KVA GPU
- Line maintenance: Avionics updates, system checks, and troubleshooting without running the APU.
- Turnaround support: Cabin servicing, lighting, IFE checks, and galleys powered cleanly while passengers board.
- Hangar work: Quiet plug-in operations during extended maintenance and inspection cycles.
- Remote operations: Engine-driven mobility for out-stations, military flight lines, and remote stands.
Key Considerations When Specifying Your Unit
- Duty Cycle & Environment
Will the unit live mostly indoors (hangar) or outdoors (ramp)? Consider weather protection, filtration, and noise considerations. - Mobility Requirements
If you frequently support remote stands, an engine-driven JTL model with robust tow gear and puncture-resistant tires can be invaluable. For fixed gates with reliable utility power, a plug-in unit streamlines operations. - Fleet Profile
A 60 kVA unit is a strong match for many business jets, regional types, and single-aisle aircraft during typical ground ops. If you regularly power heavy inrush loads or wide-body aircraft, pair the 60 kVA with higher-capacity Jetall units at specific bays. - Electrical Interfaces
Confirm cable lengths, connector types, and any need for dual-output (e.g., AC plus optional 28.5 VDC) to suit your workflow. - Maintenance Strategy
Jetall’s JTL series emphasizes easy access and common spares. Align service intervals with your shop’s PM schedule to maximize uptime.
Maintenance Tips to Maximize Uptime
- Follow the PM schedule: Filters, belts, and fluid checks (engine-driven models) should be handled proactively.
- Inspect connectors and cables: Regular checks prevent arcing, overheating, or cable damage that can ground a unit.
- Keep it clean: Dust and debris hinder cooling; periodic cleaning maintains thermal performance.
- Log output stability: If your operation tracks voltage/frequency events, use that data to fine-tune placement, cable routing, and service intervals.
