28V DC Helicopter Starting and Battery Charging
Ground Power Units
CP 28 Series
These ground power units are designed for engine starting and battery charging for helicopters, small aircrafts and military jets. The DC systems can be used as outdoors “point of use” installations at the aircraft parking stands, or indoors in maintenance hangars; avionics workshops; aircraft manufacture and training simulators, where an isolated DC power source is required.
This trolley mounted or fixed power system is designed for connection to the normal 50Hz or 60Hz mains source and provides all types of helicopters and small aircraft with a 28.5V DC high stability and isolated power supply.
This mobile power unit is designed to deliver the aircraft engine peak starting current up to 2,500A and will keep the battery fully charged whilst the aircraft is on the ground thus reducing battery stress and preserving the life expectancy of the expensive on board aircraft batteries.
The standard CP28m mobile version 28.5V DC ground power unit is constructed in a welded sturdy section steel enclosure with Ingress protection IP54 for outdoors use and for fixed indoor use the enclosure is available in IP31 or IP41.
