<p>A power supply system for uninterruptedly sensitive equipment having a supply interface with a local power line, e.g., of 230V/50 Hz. It has downstream of a high voltage/low voltage transformation station, a direct connection towards at least one Uninterruptable Power Supply (UPS), enabling elimination of the Normal/Standby switch between the local electric network and a replacement source. The UPS, which comprises batteries in parallel and a quick switching device (t<20 ms), automatically ensures the launching (or triggering) of the standby source in case of breakdown of the local electric power supply network. Reciprocally a standby source, which is directly coupled with the UPS batteries, delivers the direct current required for maintaining the charge of said batteries.</p> |
