EAC-PBB Series — Under-Bridge Unit Set (PBB-integrated 400 Hz GPU + PCA)

The EAC-PBB series addresses one of the most persistent infrastructure challenges at modern airports: how to deliver 400 Hz ground power (and optionally pre-conditioned air) cleanly to aircraft at a contact stand without trailing cables across the apron. The answer is to mount the power unit directly under the passenger boarding bridge — placing the GPU output physically above and immediately adjacent to the aircraft's ground service receptacles. ElectroAir's unit set comprises the under-bridge GPU, a remote-control panel positioned at a convenient operator location on the bridge, and a fully automated motorised cable coil that manages the output cable as the bridge extends and retracts. The coil block is mechanically decoupled from the GPU chassis, making it straightforward to adapt the cable routing to the specific bridge geometry and stand layout. The system supports 400 Hz AC power output (via the EAC converter series) and can be combined with PCA ducting, creating a single integrated mechanical assembly that covers both electrical power and cabin environmental conditioning. For airport infrastructure managers specifying new T2 or T3 terminal contact stands, the EAC-PBB system is the alternative to a floor-mounted pit unit.
