CZI TK4 cable power system for DJI M400 drone

is a professional, industrial-grade solution designed for long-term, uninterrupted flight operations. CZI TK4 allows the drone to be powered directly from the ground station via a 200 metre cable, virtually eliminating the limitations of conventional batteries and ensuring maximum reliability in the most demanding conditions.

800V high-voltage power supply for lower line losses

At the heart of the system is an 800 V high-voltage power supply, which significantly reduces energy loss and cable heating. At the same power level, the amperage is halved compared to 400 V systems and the cable heat loss is reduced by up to four times. An airborne module converts the voltage into a stable 50 V output, providing up to 4 kW of rated power, more than enough to power the DJI M400 drone and its accessories.

Robust noise immunity and stable video transmission

CZI TK4 also stands out for its robust interference immunity and stable data transmission. The system uses power line carrier (PLC) communication, allowing data rates of up to 100 Mbps. This ensures smooth and high-quality 4K video transmission even at high frame rates and bit rates. The video output is conveniently accessible from the ground station via both HDMI and Ethernet, allowing real-time connection to the control centre even in challenging radio frequency conditions.

Longer cable, higher flying height

The 200-metre cable gives the drone a significant altitude advantage, allowing aerial surveillance over a large area with better visibility. This makes the system particularly suited to security, rescue, infrastructure and event monitoring applications where continuous visibility and maximum uptime are essential.

In addition, CZI TK4 supports high power lighting solutions, providing up to 1500 W lighting output. The system is capable of simultaneously powering, for example, an 800 W ML200 and a 300 W GL300 light module, enabling efficient operation in dark or challenging lighting conditions.

To ensure safety, the system is equipped with a grounding rod to avoid induced voltages in the vicinity of high-voltage lines. The earthing conductor safely discharges unwanted electrical currents to earth, significantly reducing the risk of electric shock and ensuring safe use in different environments.

Built-in Bluetooth and Wi-Fi modules

For added convenience, built-in Bluetooth and Wi-Fi modules allow you to control the ground station via your smart device. This gives the operator flexibility and quick access to system settings, even in the field.

CZI TK4 is the ideal choice for professionals who need maximum uptime, stable power and reliable data – whether it’s for critical monitoring, rescue operations or industrial surveillance.
