Product overview
The QIHEHUI D3K from Shang Hai Qi He Hui Aviation Technology Co., Ltd. is a tethered power supply for DJI drones. Its configuration pairs a G3/G7 tethered box with a G3K onboard power supply, connecting the aircraft to power through a tether cable. The compatible aircraft are DJI M300, M350 and M400. This is a power supply product for integration with those aircraft; its identified hardware configuration consists of the tethered box and onboard supply.
The electrical specifications list a 600--810V input, 25.2/50VDC output and a 6S/12S battery designation. The D3K supports extended tethered operation, with a stated capability of 24/7 or 72-hour uninterrupted flight. Its mission equipment compatibility covers heavy-load, high-power equipment such as lighting, communications, electro-optical systems and radar. Fiber optic transmission provides a high-bandwidth, low-latency real-time HD video downlink, while rapid deployment and fly-out-of-the-box operation support emergency response applications.
