Abstract

A circuit arrangement is disclosed for the transmission of electrical supply outputs for low power devices which must be electrically separated from the mains supply. The circuit arrangement has at least one opto-electronic coupler with which low power can be transmitted with complete electrical separation. Accordingly, mains transformers can be replaced in low power operations.
