These ground power units are designed to perform starting, powering up aircraft systems and maintenance functions. When connected to AC power, the depleted batteries can be charged in a matter of hours with the built in power supply/battery charger. The 3324 contains a full 24-volt battery bank for starting and a large power supply to provide a continuous current at 28.5 Volts DC for maintenance. This will satisfy the ground power requirements of most business jets, and includes on-board air conditioning and other high draw aircraft systems. |
