Product Description

1. Adapted to drones 

1). Support flight altitude: ≥ 100m (equipped with 110m professional tethered cable, including 10m redundant length). 
2). Support takeoff weight: 10-15kg (drone power efficiency varies, this data is for reference only). 
3). Supporting flight duration: ≥ 24h (the system can support working duration, which depends on the structure and electrical fatigue resistance of the drone).

2. Typical characteristics

2.1 Lightweight and Portable, Fast deployment 
Adopting a lightweight design, it is compact in size, lighter in weight, and can be easily carried by one person. It supports rapid deployment in the field and meets the needs of mobile missions. 
2.2 Multiple Protections, Safe and Reliable 
Electrical isolation: design with complete separation of AC high voltage and DC low voltage electricity.
Equipped with multiple protection mechanisms such as input overvoltage/undervoltage, output overcurrent/short circuit, etc., automatic fault detection and recovery ensure stable system operation. 
Ultra High Voltage Withstand Standard ≥ 3000VDC; 

2.3 Low Voltage Button to Start AC Input, No Need AC Air Switches, Improve The Safety. 

2.5 Stable Power Supply and Long-lasting Battery Life 

Adopting low-voltage soft starting mode, replacing traditional circuit breaker starting, with ultra-high waterproof rating far superior than air switches, further improving the safety of isolated AC contact use. 
2.4 Touch Screen Display 4.3-inch: 
Real time display: electrical parameters such as real time 
power/voltage/current/temperature/cable length/power consumption/running time. 
Operating data curve chart: Voltage/current/temperature curve chart. Fault record. Logs storage and read.

The onboard module provides constant voltage output, that avoids ineffective charging and discharging losses, protect battery lifespan, and always maintain a fully charged standby state during operation. 
2.6 Intelligent Winch Automated Control System 
Automatically follow the takeoff and landing of the drone to retract cables. 
Fully automated operation process, unmanned aerial vehicle takeoff and landing do not require manual operation throughout the entire process, reducing operational barriers and improving task efficiency

2.7 Worry-Free Power Cut Off, Intelligent Cable Retraction 

Built in backup power supply, it can automatically switch to backup power mode in case of sudden power outage, completing emergency wire retraction and avoiding the risk of cable entanglement. 
2.8 Intelligent Communication Management System 
Wired communication between GCS and ground power station: USB Type-C or RJ45 high-speed transmission. 
Wireless communication between GCS and ground power station: Bluetooth 5.0 low-power connection. 
Optic fiber wired communication between GCS and drone: Optic fiber. Achieve fast data transmission.
