Featuring an advanced 800V high‑voltage power supply, the TK4 system significantly reduces line loss while delivering stable power to support long‑duration aerial missions and high‑power payloads.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003ch3\u003e800V High‑Voltage Power Supply for Lower Line Loss\u003c\/h3\u003e\n\u003cp\u003eThe TK4 tethered system operates with an 800V high‑voltage transmission design. At the same power level, the current required in an 800V system is only half that of a traditional 400V system, reducing cable heat generation to approximately one quarter. The airborne unit outputs a stable 50V power supply with up to 4 kW of rated power, ensuring reliable performance for the DJI M400 and its payloads.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003ch3\u003eStable Video Transmission with Strong Anti‑Interference\u003c\/h3\u003e\n\u003cp\u003eThe ground station and airborne unit communicate using Power Line Carrier (PLC) communication, providing bandwidth of up to 100 Mbps. This supports high‑frame‑rate, high‑bitrate 4K video transmission. Video signals can be output from the ground station through HDMI or Ethernet directly to the command center, while strong resistance to radio‑frequency interference ensures stable and reliable transmission.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003ch3\u003eLonger Cable for Higher Flight Altitude\u003c\/h3\u003e\n\u003cp\u003eThe TK4 system includes a standard \u003cstrong\u003e110‑meter tether cable\u003c\/strong\u003e, with optional configurations extending up to \u003cstrong\u003e200 meters\u003c\/strong\u003e. This extended cable length enables higher flight altitudes and improved operational flexibility, allowing drones to perform tethered aerial monitoring at heights of up to 200 meters.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003ch3\u003eSupports High‑Power Lighting Payloads\u003c\/h3\u003e\n\u003cp\u003eDesigned for demanding aerial lighting missions, the TK4 tethered power system provides an upgraded lighting output of up to \u003cstrong\u003e1500 W\u003c\/strong\u003e. It can simultaneously power lighting combinations such as an \u003cstrong\u003e800 W ML200\u003c\/strong\u003e and a \u003cstrong\u003e300 W GL300\u003c\/strong\u003e, delivering powerful illumination for nighttime operations, emergency response, and surveillance missions.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003ch3\u003eGrounding Rod for Enhanced Operational Safety\u003c\/h3\u003e\n\u003cp\u003eWhen operating near high‑voltage power lines, tethered drone systems may experience induced voltage that can pose safety risks. The TK4 includes a \u003cstrong\u003egrounding rod\u003c\/strong\u003e designed to safely discharge induced current into the earth. The system uses a standard grounding interface, allowing operators to select grounding rods suitable for different terrains and operational environments.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003ch3\u003eWireless Connectivity with Bluetooth and Wi‑Fi\u003c\/h3\u003e\n\u003cp\u003eThe TK4 Tethered Power System integrates \u003cstrong\u003eBluetooth and Wi‑Fi connectivity\u003c\/strong\u003e, allowing users to connect to the ground station using a smartphone or mobile device. This enables convenient system monitoring and control, improving operational efficiency during field deployments.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003ch3\u003eIdeal Applications\u003c\/h3\u003e\n\u003cp\u003eThe CZI TK4 Tethered Power System is ideal for aerial surveillance, emergency response, infrastructure inspection, disaster monitoring, event security, and continuous aerial lighting missions. By delivering reliable continuous power and stable data transmission, it enables drones to remain airborne for extended operations without battery limitations.\u003c\/p\u003e","brand":"CZI","offers":[{"title":"110m","offer_id":52114577654034,"sku":null,"price":16919.0,"currency_code":"CAD","in_stock":true},{"title":"200m","offer_id":52114577686802,"sku":null,"price":18328.0,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0754\/1882\/9074\/files\/czi-tk4-tethered-power-system-1227197250.png?v=1773428830","url":"https:\/\/www.infinitdrones.com\/products\/tk4-tethered-power-system","provider":"Infinit Drones Corp","version":"1.0","type":"link"}
