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 integrated BA controller. This ACP provides in a single unit the protection of the controller, the control and the connection to the devices. The BA controller is used to create simple source-changeover system that switch from one source to another depending on the presence of voltage UN on the “Normal” source. The BA controller is generally used to manage two permanent sources. The control voltage is from 380VAC to 415VAC 50/60Hz, or 440VAC 60Hz.
