2. Wiring Instructions
InputAirborne Power Supply Input Terminal: As shown in the figure above, use 14AWG silicone wire with XT90 connector, and connect it to the DC 400V output terminal of the tethered box.
2Airborne Power Supply Output Terminal: As shown in the figure above, use 8AWG silicone wire to connect to the UAV (Unmanned Aerial Vehicle) power supply (48V), and it can be directly connected in parallel to the main power circuit of the battery power supply.
Note: For the AS150U output plug, the 4 middle signal wires are connected in parallel to serve as the main power voltage sampling wire. If there is a conflict with the user's signal, please remove this signal wire to avoid damage to the equipment.
3. Usage Precautions
- For the UAV, the backup battery must be powered on first, then the main power supply. If the main power supply is powered on directly, large UAV systems may fail to start the main power supply due to inrush current.
- Try to ensure that the voltage of the backup battery is above 47V when starting. If the voltage is too low, the charging current will be too large after the main power supply is powered on, which will affect the battery life. If the voltage is extremely low (e.g., below 45V), it may cause the power supply to fail to start.
It is strongly recommended to operate with a fully charged battery every time, which is the most appropriate way.
- During normal tethered hovering, the UAV power voltage is approximately at a stable state of over 48V, and the battery capacity is about 70%. Please correctly calculate based on the battery capacity whether the backup battery has enough power to meet the forced landing requirements in case the main power supply is abnormally cut off.
- After the completion of the tethered mission, pay attention to the maintenance of the backup battery.
