Introducing CZI TK3-M350 Tethered Power System for DJI M300/M350 RTK

The CZI TK3 represents the new generation of ground power systems. Engineers optimized it further for size and weight. It converts 110V–220V AC power into 400V DC high-voltage power and transmits it to the drone through a high-performance nickel alloy cable. This setup enables the drone to achieve 24-hour uninterrupted flights.

When paired with UAV matrix lights, high-power gimbal searchlights, cameras, and other mission payloads, the TK3 easily meets the demands of long-duration and wide-area emergency lighting and monitoring—even in complex emergency scenarios.

✔ Lightweight Design – First, it replaces one primary battery without adding extra weight to the drone.

✔ 24-Hour Uninterrupted Flight – Then, it converts 110V-220V AC power into 400V DC high-voltage power, ensuring long-duration operations.

✔ High-Performance Cable – Next, it uses nickel alloy cable for efficient power transmission.

✔ Emergency Lighting & Surveillance – Moreover, it proves ideal for extended UAV operations with matrix lights, high-power searchlights, and cameras.

✔ 80m Cable Length – Additionally, you can extend it with an optional 30m extension cable for greater operational flexibility.

✔ Power Failure Alarm – In case of power failure, it triggers an audible 2-minute buzzer alarm.

✔ 5-Inch High-Brightness Display – Furthermore, its 500 nits brightness allows clear viewing in sunlight.

✔ Multiple Power Supply Options – It also supports energy storage devices, 220V utility, and alternators.

✔ Foldable Quick-Release Waterproof Bracket – Plus, it offers easy setup and portability.

✔ Overcurrent Protection – If output current exceeds 65A, it performs an automatic safety shutdown.

✔ Compatible Drone Models – It works seamlessly with DJI M300, M350, M30, and M30T.

✔ Remote Upgrade Capability – Finally, it supports wired and wireless OTA updates for seamless performance improvements.
