Product overview
The Shanghai Qi He Hui Aviation Technology Co. G15 Tethered Power System combines a tethered box, tether cable and onboard power supply. The box accepts 380VAC ±10% at 50Hz and provides 200–1000VDC, with a factory setting of 1000VDC. Its rated power is 15KW and peak power is 20KW. The 650/480/302mm enclosure weighs 36Kg. A touchscreen presents voltage, current, power, temperature, cable status and working status, giving the operator a central display for the system’s electrical and operating information.
Aircraft integration requires space for a 295/197/59.5mm onboard supply weighing 2.6Kg, with external leads and pre-drilled M3 threaded mounting holes. This supply accepts 800–1000VDC and delivers 50/59VDC at 12KW; its input range therefore covers only the upper portion of the tethered box’s output range. Standard cable lengths are 110/220m, with custom lengths, interfaces and mounting options available on request. The 4.3mm tether weighs 26g/m and carries a 15A specification. The system’s specified takeoff-weight range is 45–60Kg.
