Today's aircraft make the most extensive use of electronics imaginable. The electronics, combined with other heavy electrical loads aboard, place very high demands on the ground power source. In addition to heavy ground power loading, the newer aircraft are able to produce high level power transients as part of their normal operation.

The Gate Box addresses all of the latest aircraft ground power requirements. The digital circuitry within the Gate Box will not permit the aircraft to be connected to power that is out of limits. If ground power limits are exceeded while the aircraft is on-line, power to the aircraft will be interrupted by the Gate Box. Without compromising safety, nuisance tripping is safely eliminated.
