DC voltage feeder for low-voltage and high-current consumers, with active output current regulation, remotely settable on PROFINET BUS.

The apparatus performs conversion of three-phase line voltage to a DC source with output currents up to 1000A.

The double active electrical conversion and galvanic isolation between input and output allow very fine output power stability, as well as the possibility of increasing the system power with an apparatus modularity of up to four converters, in series/parallel configurations depending on the voltage and current requirements to be obtained.

This type of Mesar power supply is currently used to serve hydrogen and oxygen production electrolyzers.
