Combined AC+DC Ground Power Units for flexible apron operations
ElectroAir’s EACR combined power supply units deliver both 28.5 V DC and 400 Hz AC from a single system to support aircraft and helicopters during pre-flight preparation, MRO tasks, production floors, and training simulators. Channels are independent, can be used simultaneously, and feature separate voltage-drop compensation for stable output under varying loads and cable lengths. The DC output can operate in 28/56 VDC dual-channel mode or as a single 28.5 VDC channel.
