Socomec’s IP+ Rail (OLI) offers increased energy availability:  the system can take inputs from both a 25 kV overhead line as well as a 400V AC mains supply.

As a result, this solution potentially avoids the need for a diesel generator and its associated maintenance, fuel storage and refuelling costs.

The innovative rectifier stage converts the input voltage into a DC voltage that will charge both the UPS battery and supply the input stage of the inverter.

In normal mode*, the upstream voltage of the rectifier corresponds to the transformed single phase voltage of the overhead line. The transformer and voltage stabiliser eliminates voltage sags and surges related to current draw of locomotives. When this voltage is not present or is no longer with intolerance, it is the 3 phase DNO supply which is sent directly to the UPS rectifier.

The inverter converts the DC voltage, provided either from the rectifier output or from the battery in a perfect sinusoidal voltage distributed to the critical loads. The UPS is also equipped with an automatic bypass which allows a no-break transfer of the load directly onto the mains supply in case of overload or faults.

An external manual bypass completes the solution to allow for maintenance of the UPS.
