Abstract:
A system for reconnection of a load after a disconnection due to a mains power failure, the system comprising at least one rectifier, at least one battery and at least one load, characterized in thatthe at least one load is directly connected to the at least one rectifier delivering current controlled DC power during normal mains operation; the at least one battery is via a power switching member (C1-Cn) connected directly to a group (1-n) containing at least one load and at least one rectifier, whereby after a disconnection of the at least one battery (B1-By) by the power switching member, a reconnect will not occur until the at least one rectifier has delivered current controlled DC power which has driven an input of the at least one load of the group up to a voltage level close to the voltage of the at least one battery to thereby limit inrush current and obtain an almost transient-free reconnection of the load of the group to the at least one battery.
