DC to DC Converter with Screw Terminals

Quick Overview

The SD-15X are single output panel-mount isolated DC/DC Converter Modules supplied in a well ventilated metal casing. This DC to DC converter can be used to converter a 9-72vDC power supply to a 5vDC, 12vDC or 24vDC power supply. Ideal applications are for converting a 12V solar panel, battery bank or alternator power supplies to a 24vDC power supply. Units can also be used to provide a stable regulated supply from an unregulated supply. Max output is 15W with short circuit, overload and over-voltage protection.
