CZI Tethered Power System TK4 for DJI Matrice 400
The CZI TK4 Tethered Power Station delivers continuous, uninterrupted power to your DJI Matrice 400, eliminating battery constraints for extended operations. This robust system converts AC mains into high-voltage DC, transmitted via reinforced tether cables to support demanding payloads and high-power propulsion systems. Built for reliability in challenging environments, it features an intuitive HD display for real-time monitoring, integrated backup power, and exceptional durability. Ideal for critical applications including emergency response lighting and round-the-clock security surveillance, the TK4 enables your M400 to maintain operational capability for as long as your mission requires.
800V High-Voltage Power Supply for Lower Line Loss
The TK4 Tethered Power System adopts an 800V high-voltage power supply. At the same power level, the current of an 800V system is half that of a 400V system, while cable heat generation is reduced to one quarter. The airborne unit delivers a stable 50V output with a rated power of 4 kW, providing ample and reliable power for the DJI M400 and its payloads.
Longer Cable, Higher Flight Altitude
The TK4 system comes standard with a 110 m tether cable, with optional configurations up to 200 m. This allows the drone to operate at greater heights, making tethered aerial monitoring at 200 m more efficient and flexible.
Grounding Rod Included to Eliminate Induced Voltage
When operating near high-voltage power lines, tethered systems may be subject to induced voltages ranging from tens to even hundreds of volts, posing a risk of electric shock to operators. The TK4 system is equipped with a grounding rod. By inserting the rod into the ground, induced current is safely discharged into the earth, effectively reducing the risk of electric shock. The system uses a standard grounding interface, allowing users to select grounding rod of appropriate length based on on-site conditions, ensuring reliable grounding across different terrains.
Strong Anti-Interference Capability with Stable Video Transmission
The ground station and airborne unit communicate via power line carrier (PLC) communication, supporting 100 Mbps bandwidth, which meets the requirements for high-frame-rate, high-bitrate 4K video transmission. Video output can be delivered from the ground station via HDMI and Ethernet directly to the command center. With excellent resistance to radio-frequency interference, transmission remains stable and reliable.
Supports Higher-Power Lighting Combinations
The TK4 Tethered Power System features an upgraded lighting power output with a maximum of 1500 W. It can simultaneously support an 800 W ML200 and a 300 W GL300, delivering powerful combined illumination for demanding missions.
Built-in Bluetooth and Wi-Fi Modules
The TK4 Tethered Power System integrates Bluetooth and Wi-Fi modules, enabling users to connect to the ground station via a smartphone and operate the system directly from a mobile device.
