SD-15A Series - 15W 9.2~18VDC Input Single Output DC-DC Converter



SD-15 Series are 15W DC/DC comverters that comply with LVD and EMC directives and bear the CE mark. Featuring 2:1 wide DC input range and 3000VDC input/output isolation SD-15 securely transfers a wide range of DC input voltage ratings into a stable DC output. The miniture design also gives end users a huge advantage of saved installation space. With the standard function of short circuit, over load and over voltage protections SD-15 is ideally suited to a wide variety of fields from general electrical engineering usage, automotive, security and all kinds of battery back-up applications.
