SECTION 1 M51A OPTION OVERVIEW 1.1 Introduction This addendum is to be used in conjunction with the DLM 600W Series Power Supplies Operation Manual, Sorensen Document No. M362161-01. The Sorensen M51A Option for the DLM 600W Series power supplies provides a remote analog interface, which has safety isolation from the output terminals. This allows the remote analog interface to be connected to user accessible (SELV) control circuits, even though the output terminals were floated at a
