PUBLIC SAFETY ACCESSORY
TK3-X500 tether
A drone that stays up all night.
The new-generation TK3 converts 220 V AC power into 400 V high-voltage DC and sends it to the drone through a high-performance nickel-alloy power cable, enabling continuous flight for up to 24 hours. Used with matrix lights, high-power searchlights or gimbal cameras, it gives long-duration emergency lighting and monitoring.
