Safe & Reliable

Contactless · multiple protection

The G70‑M400 Tethered Power Station is a dedicated tethered power supply system designed for the DJI Matrice 400 drone. It consists of a tethered winch box (ground module), an airborne power supply (air module), and optional mission payloads such as the L24 floodlight.

The system operates at 850 VDC, using a lightweight, low‑drag tether cable that reduces the drone’s payload. Its key advantage is extreme ease of use – no manual operation of the tethered equipment is required throughout the entire flight, enabling truly automatic cable retraction and deployment. The intelligent AI‑driven speed and torque control supports a cable speed of up to 5 m/s, effectively preventing cable sag, oscillation, severe swinging, and sudden tension spikes, ensuring contactless safe operation.

The product features ultra‑long flight time (>24 hours), portability, rapid installation, stable voltage supply, and multi‑terminal interconnection. Multiple safety protections are built‑in, such as automatic high‑voltage shutdown upon cable breakage/short circuit/disconnection, and automatic cable recovery via backup battery in case of external power failure, guaranteeing safety and reliability for extended tethered missions. It supports various payloads including floodlights, searchlights, speakers, communication modules, and more, making it ideal for long‑duration inspection, security surveillance, emergency lighting, and other applications.

Frequently Asked Questions
Q1: Is the operation complicated?
Not at all. No operation on the tethered equipment is required from takeoff to landing. No need to erect poles, pull out large amounts of cable, adjust torque knobs, or preset voltage, resistance, tension, or speed. The pilot simply flies the drone while the winch box automatically handles cable retraction/deployment and high‑voltage switching.
Q2: How does the automatic cable retraction work?
The cable automatically adjusts tension during takeoff and landing, synchronising retraction and deployment with the drone’s movement. Unlike products that require manual gear settings or button presses, our system is fully automatic with no human intervention.
Q3: Is it safe to use in strong wind?
Yes. The cable remains under tension, flexing with the wind and returning to its original position when the wind subsides, so the drone experiences no additional pull. Without tension, the cable would swing violently and impose erratic forces on the drone, risking propeller contact.
Q4: Is the high‑voltage cable safe?
Never touch the cable during operation. Although it has insulation and high‑voltage breakdown resistance, leakage can still occur in wet conditions or if worn. Even with insulated gloves, contact is dangerous. Our system is strictly contactless – no personnel need to approach or touch the cable.
Q5: Is the power supply stable and reliable?
Yes. The airborne module provides a stable 51.3V or above throughout the flight, so the tethered battery never needs charging or replacement between extended missions.
Q6: What safety protections are included?
Comprehensive protections include:
· Fully automatic cable retraction – no contact with high voltage.
· Operators focus solely on the drone, improving safety and concentration.
· Backup battery automatically retracts the cable if external power fails.
· Contactless operation keeps personnel away from high voltage.
· High‑voltage automatically cuts off upon cable break, short, or disconnection.
Q7: What communication and control methods are supported?
The system supports multi‑terminal interconnection and smart display control. You can operate via buttons, App, HMI, or the drone’s remote controller (with display, setting, and control capabilities).
