Aviation Control Cabinet – & UPS Cabinet

Reliable control and uninterrupted power

The Quantec Aviation Control Cabinet for wind turbines combines the uninterruptible power supply (UPS) and energy storage for the obstacle lighting system in a single cabinet. It provides all connections needed to link every component of the system and can also provide additional functions via a USB stick.

* The available output power depends on temperature and operating mode. The power adapter delivers 10 A at 25 °C and 7 A at 55 °C. When the built-in battery is charging, the output current must be reduced by 2.7 A. Total: max. 4.3 A.

** The usable battery capacity depends on temperature and discharge current. Low temperatures and/or high discharge currents can significantly reduce capacity. Ideal: 20–25 °C.
