The UA controller is used to create a sourcechangeover system integrating the following automatic functions:
1) transfer from one source to another depending on the presence of voltage UN on the “Normal” source
2) startup of an engine generator set
3) shedding and reconnection of non-priority circuits
4) transfer to the “Replacement” source if one of the phases on the “Normal” source fails. The UA controller can control Compact NS, Compact NSX and Masterpact NT/NW devices.
