ASSEMBLY OF ACTUATORS AND OF A SYSTEM FOR SUPPLYING ELECTRICAL POWER FROM A NETWORK

摘要

An assembly having actuators and an electricity power supply system. The assembly includes an input unit connecting the actuators to a three-phase AC electricity network and to a control system. The input unit includes a transformation member arranged to transform the AC into DC at high voltage and connected to a bidirectional power line having connected in series therewith at least one protective switch, a communications interface, and at least one of the actuators. The communications interface is arranged and connected to a central unit to exchange signals over the power line with a signal communications interface of at least one of the actuators. The input unit also includes a charger/discharger unit that connects an energy store to the power line.
