It is a remote controlled source changeover system for Compact NSX, Compact NS and Masterpact devices. It is composed of an ACP plate and of an automatic UA controller. This ACP provides in a single unit the protection of the controller, the control and the connection to the devices. The UA controller is used to create a source-changeover transfer from one source to another depending on the presence of voltage UN on the “Normal” source. UA controller integrates also the start up of an engine generator set, the shedding and reconnection of non-priority circuits, the transfer to the “Replacement” source if one of the phases on the “Normal” source fails. The control voltage is from 220VAC to 240VAC 50/60Hz.
