1.Typical characteristics


3). The operation is simple, and the entire process of drone takeoff and landing does not require the operation of the ground module. The button type take-up function is also available.
4). The onboard power supply has a constant voltage output, and the backup battery has no charging or discharging phenomenon throughout the entire process, without losing power or causing hidden damage.
2.Adapted to DJI Mavic 3
1). Support flight duration: ≥ 12h.
2). Support flight altitude: ≥ 30m (tether cable 33m, reserved safety length).
3). Optional lighting group: 200W (JM200).
3.Functional characteristics
1). Cable reel in&out function: Passive wire reel out, long press the button to automatically reel in cable, and manually winding in case of power loss. 2). Protection function: Input overvoltage and undervoltage protection, output overvoltage, overcurrent, short circuit, over temperature protection, fault elimination and self recovery.
3). Fault alarm function: The system fault alarm light flashes red and beeps to alert.
4). Equipment portability: With a backpack design, the backpack can be equipped with a complete tethering system that includes a tethering box, onboard power supply, lighting unit (optional), and other accessories. The overall weight is 5.0 ± 0.2kg.
