Abstract
The present invention concerns an electrical installation or device equipped with a power supply unit comprising a voltage converter having primary and secondary parts respectively defining a primary side and a secondary side of this electrical installation or device. This power supply unit comprises a power management unit arranged on said primary side, the primary part of the converter being associated with a control circuit also arranged on said primary side and controlling the electrical energy flowing in the primary power path of said primary part. The control circuit receives from the power management unit at least a first control signal for switching OFF the electrical energy in said primary power path, said power supply unit entering a very low power mode ('Power-down' mode) when said first control signal is set to OFF so that the converter is not supplied anymore. The power management unit is arranged such that, in said very low power mode, it can receive or generate at least a wake-up signal and set to ON said first control signal in response to said wake-up signal for supplying again said primary and secondary parts of the converter.
