DJI M400 RTK Drone with Tethered Power Station: Supports Stable 48-Hour Continuous Hovering

Tired of drone hover time limits derailing long-duration tasks? The DJI M400 RTK Drone, paired with its tethered power station, solves that—delivering stable 48-hour continuous hovering. No more frequent landings for recharging; it stays reliably airborne, ideal for round-the-clock surveillance, high-altitude mapping, or non-stop monitoring. Cut downtime, keep operations smooth, and focus on core work.

Basic Info.

1. Adapted to DJI M400RTK

1). Support flight altitude: ≥ 100m (equipped with 110m professional tethered cable,

including 10m redundant length).

2). Support flight duration: ≥ 24 hours (actual endurance is affected by the structural

strength and electrical system durability of the drone).

3) . Optional lighting: 800W.

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.

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.

2.5 Stable Power Supply and Long-lasting Battery Life

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 module: USB Type-C or RJ45 high-speed transmission.

Wireless communication between GCS and ground power module: Bluetooth 5.0 low-power connection.

Optic fiber wireless communication between GCS and drone: Optic fiber. Achieve fast data transmission.
