Abstract:
1. An electrical assembly comprising an installation comprising an alternating current power supply port and at least one electrical system, and an uninterruptible power supply device for supplying without interruption with alternating current the power supply port, the uninterruptible power supply device comprising: a first circuit for electrically connecting the alternating current power supply port of the installation to an alternating current power supply network; and a back up device comprising a rectifier, means for charging, means for storing and means for electrical energy, and an inverter connectable to the alternating current power supply port of the installation, wherein the back up device is arranged in a second alternating current supply circuit connectable to the alternating current power supply port in a by-pass of the first circuit, wherein the uninterruptible power supply device comprises a switch arranged and commanded to connect selectively the first or the second circuit to the alternating current power supply port as a function of a state of the power supply of the electrical system in the installation, wherein each electrical system of the installation consumes direct current and is electrically connected to the alternating current power supply port through a direct current power supply device with AC/DC conversion, wherein the switch is commanded to connect selectively the first or the second circuit to the alternating current power supply port as a function of a state of the supply with direct current of the electrical system in the installation, and wherein the installation further comprises at least one module for managing the power supply of the electrical system designed to transmit an information message on the state of the direct current power supply of the electrical system to a controller of the switch, said controller being located upstream of said AC/DC conversion.
