Product overview
Shanghai Qi He Hui Aviation Technology Co.’s G1 Tethered Power System combines a tethered box, tether cable and onboard power supply for electrical power delivery. The box measures 361x271x212.5mm and weighs 8Kg. It accepts 190--240VAC, with single-phase 220VAC and 50/60Hz specified, and provides 200--400VDC with a factory setting of 380VDC. Box power is rated at 1.5KW, with a 1.8KW peak. Its touchscreen displays voltage, current, power, temperature, cable status and working status. Standard cable lengths are 18/33m; custom lengths are available upon request.
The onboard supply measures 92/52/29.5mm and weighs 190g, defining its installation footprint and mass. It accepts 340--400VDC and provides 17.2/25.2VDC, with power specified as 600W. External leads and pre-drilled M3 threaded mounting holes form the standard integration provisions; custom interfaces and mounting options are available upon request. The 2.2mm tether weighs 8.2g/m and carries a 2A current specification. Its construction includes multi-strand silver-plated steel wire, composite fluoroplastic insulation, high-temperature Teflon insulation and a Kevlar reinforced braided layer. The system’s specified takeoff-weight range is 1--3Kg.
