Product overview
The CZI TK4 Tethered Power System supplies electrical power to a UAV and its payloads, with an emphasis on sustained aerial lighting. Its highly integrated design uses an 800V high-voltage platform intended to reduce cable transmission losses. A dedicated backpack supports transport by hand or on the shoulders. The standard configuration includes a 110 m cable, with a 200 m option, and a dedicated grounding stake for directing induced electricity into the ground in high-voltage environments.
Lighting specifications include a maximum output of 1500W and a maximum illuminated area of 15836m². The supported lighting combination is stated separately as two 800W ML200 matrix lights operating simultaneously. A 5.5-inch touchscreen displays output power, lighting brightness and cable retraction strength in real time. Integration with the CZI C30N night-vision camera supports extended monitoring and HDMI video delivery to a command center. A 65W Type-C output supports fast charging and emergency power for mobile devices.
