Sorensen, a division of Elgar, introduces a free graphical user interface (GUI) for its DLM and DCS families of programmable DC power supplies. The Windows executable program allows users of the DLM and DCS power supplies to control the power supply’s programming, monitoring, and operation from a PC through an IEEE or RS 232 interface without needing SCPI commands. Users can program voltage, current, and overvoltage protection and read back both voltage ad current measurements.
