Universal power supply system
View Patent ↗A universal power supply system is used for at least one electric consumer. The supply system comprises at least one AC source and a cable connection connecting said AC source to said electric consumer. The AC source has associated therewith an AC/DC converter for converting the AC voltage into DC voltage.
