Compared with other types of drones, tethered drones can stay in the air for a long time without being limited by electrical energy due to its cables, and have obvious advantages in emergency communication, high-altitude surveillance, environmental monitoring and others.
Tethered drones are expensive and have complex applications. Once there is some problem in power supply system, precision sensing or flight control system on board may occur. And in some cases there is even a risk of crashing. Therefore, in order to avoid high losses, engineers designing drones have higher requirements for the quality of the power supply.
After comparisons, the engineers of a UAV manufacturer finally chose APM high power DC power supply.
APM high power DC power supply features high power density, high reliability, high accuracy, perfect operation interface, and excellent testing performance, which can comprehensively meet different testing requirements, simulate various normal and abnormal working environments, and measure important electrical parameters for the production of quality UAV.
