Power supply concept
The u-control controllers and the u-remote modules use three
internal current paths as described in following chapter4. In-
put and output paths are supplied seperately, therefore a cus-
tom-t refreshing by power-feed modules is easyly feasible.
The gure shows the general supply concept. For detailed
description and calculation of the current demand please
regard sections 4.6 and 4.7.
