On this page you can read about the main types of Ground Power Units (GPUs), selecting the right GPU, advantages of modern GPU, and best practice for maintenance of GPUs.
Types of Ground Power Units
By Power Output Type
400 Hz AC GPUs
These units provide 400 Hz alternating current power, the standard for most commercial aircraft:
- 115/200V 3-phase AC power
- Suitable for commercial passenger aircraft
- Available in various capacity ratings from 30 kVA to 180 kVA
- Compatible with point-of-use and centralized power systems
28V DC GPUs
These units deliver 28 volt direct current power required by many smaller aircraft and military applications:
- 28V DC output matching aircraft battery systems
- Common for business jets, regional aircraft, and military applications
- Available in solid-state and battery-powered configurations
- Capacity options to match diverse aircraft requirements
Combination Units
Our product range includes combination units that can deliver both 400 Hz AC and 28V DC power:
- Flexible power delivery for mixed fleets
- Space-saving design reducing apron equipment footprint
- Simplified maintenance with unified systems
- Optimized investment for diverse operational needs
By Mobility Type
Mobile Ground Power Units
Mobile GPUs offer flexibility for changing operational needs:
- Fully mobile design with tow bars or integrated wheels
- Quick deployment anywhere on the airfield
- Ideal for remote stands or contingency operations
- Available in diesel, electric (with cable), and battery-powered versions
Fixed Electrical Ground Power Units
Fixed units are permanently installed at gates or in hangars:
- Integrated into airport infrastructure
- Maximum reliability with protected installation
- Zero apron congestion with under-jetway or in-ground systems
- Optimized for high-usage positions with continuous operation
Vehicle-Mounted GPUs
These specialized units are integrated into service vehicles:
- Rapid response capability for aircraft in any location
- Combined functionality with other ground service equipment
- Efficient use of airport resources with multi-function vehicles
- Enhanced operational flexibility for busy airfields
