Product Description

Future-Proof Your Drone Operations Simplified Tether Power System

the "Future-Proof Your Drone Operations Simplified Tether Power System" is a specialized power delivery solution designed to provide a steady, uninterrupted flow of electricity from a ground-based source to an airborne vehicle. This technology ensures precise flight control, maintains a constant voltage supply to sensitive onboard systems, and supports optimal overall performance, making it particularly valuable for applications where reliability, endurance, and accuracy are paramount.
 

I,Typical Characteristic 

 

1.Simple operations,the entire process of drone taking off and landing does not require the operation of ground module .

 

 2.Comprehensive input /output protection,fault elimination and self recover. 

 

3.Fully automatic take up and pay off function,the wire can be rewound under power loss.

 

 4.The air module power supply has a constant voltage output,and the back up battery has no charging and discharging phenomenon.

II,Adapted drone
1.Supporting flight altitude:≥200/300m(tethered cable length220/330m,reserve safe length.).
2.Supporting takeoff weight:60~90kg(UAV force effect varies, this data is for reference only.).
3.Supporting flight duration:≥48h(he system can support working hours depending on the structure of the UAV and the electrical fatigue resistance).

III,Function characteristics
1.Protection functions:Separate design for strong and weak electricity.input over voltage and under voltage protection,output over voltage ,output over current,output circuit,output over temperature protection,input and output voltage resistance≥3000VDC,tethered cable insulation voltage resistance≥3500VDC.
2.Data communication:wired and wireless communication function,Support remote display and control,client-side data viewing and downloading.Optional fiber optic communication.
3.Data display function:The touch screen displays data such as output voltage,output current,output power, cable outlet length,working duration,installation temperature,total power consumption,fault record,and working status information.
4.Set and adjustment:the display screen supports setting and adjustment the parameters such as take-up and payoff tensile and speed,data and time,output voltage,safety lengths,warning temperature,ect...,and support the switching between Chinese and English.
5.Alerts and reminds:Failure the screen displays the contents of the fault,the buzzer strong sound reminder.
6.Automatic take-up and payoff:following take off and landing of the drone to synchronously tethered cable take-up and payoff,adjusting the tension auto management,and manually press the button to reaction the cable while power cut off.
7.Carry and transport:The box is equipped with a handle and foot pads, optional folding trailer, trolley wheels for transportation.
8.Power supply is optional 25000W/100L diesel generators (specifications attached)
