High-Power 30kW Tethered Drone Power Supply System 300m Max Altitude UT35/60/80/100/200

The MH-series Tethered Drone Power Supply System is a complete airborne-ground solution that includes an MH-series multirotor drone, a tethered airborne unit, and a high-power tethered ground station. Engineered for extended missions, the system delivers continuous high-voltage power through a robust tether cable, ensuring stable power transmission and a secure physical link between the UAV and ground station.

This industrial-grade tethered power solution offers five modular configurations, supporting power outputs up to 30kW and maximum altitudes ranging from 120m to 300m. Each configuration includes an airborne unit paired with either a compact suitcase-type station or a ruggedized industrial power enclosure. The system’s automatic cable length adjustment and adaptive voltage compensation enable safer, longer, and more efficient UAV operations—making it ideal for firefighting, signal relay, and security surveillance where battery-free continuous flight is required.

Product Introduction

With advanced safety protections including over-voltage, over-current, short-circuit, and over-temperature alarms, the MH-series system ensures reliable and protected operation in challenging environments. Additional features such as manual cable retraction, IP54-rated protection, and military-grade shockproof housing enhance durability and field readiness. Real-time voltage, current, cable length, and temperature metrics are displayed via a built-in interface or dedicated PC software for remote monitoring and diagnostics.

⚠ Note: LG55/LG70 units require a 220V AC input via industrial plug. For 110V regions, a voltage converter (110V to 220V) is needed. Ensure local plug type and voltage are confirmed in advance. Input current must not exceed 16A.

Product Details

Tethered Drone Power Supply System MH-Series Drone+Airborne unit+Tethered Ground Station

This tethered power solution is tailored for multirotor UAVs, delivering safe, stable, and extended flight durations. By transmitting continuous high-voltage power through the tether cable, it ensures uninterrupted energy flow while maintaining a secure physical connection between the drone and the ground station.

Compact & Industrial Ground Stations

Delivers a high output of up to 30kW with a maximum altitude capability of 120–300m. Engineered for long-endurance performance in demanding industrial drone operations.

Smart Cable Management

The tether system automatically adjusts cable tension during drone takeoff and landing to maintain safety and stability throughout operation.

Optical Fiber + Power Integration

Integrating optical fiber with power transmission enhances resistance to electromagnetic interference, increases transmission distance and bandwidth, and supports faster data rates. (Optical fiber is optional.).

Fiber Optic Module Connection

The Ethernet port connects directly to ground equipment. Fiber Optic Port B links to the drone-side; Port A connects to Fiber No.1 in the tether. Ensure all ports are firmly connected for optimal performance.
