The output is fully isolated from the dc dc dc input, allowing versatile polarity configurations and grounding connections. The modules exhibit high efficiency of 91% typical at full load. Built-in filtering for both input and output minimizes the need for external filtering. The module is fully self-protected with output over-current and over-voltage, over-temperature and input under voltage shutdown control. Optional features include negative or positive on/off logic and SMT connections. * Trademark of general Electric Company UL is a registered trademark of Underwriters Laboratories, Inc.

Page 1 Data Sheet GE KSTW010A0A Barracuda Series DC-DC Converter Power Modules 36-75Vdc Input 5.0Vdc, 10A Output Absolute Maximum Ratings Stresses in excess of the absolute maximum ratings can cause permanent damage to the device. These are absolute stress ratings only, functional operation of the device is not implied at these or any other conditions in excess of those given in the operations sections of the data sheet. Exposure to absolute maximum ratings for extended periods can adversely affect the device reliability.

An input line fuse must always be used. This power module can be used in a wide variety of applications, ranging from simple standalone operation to being part of complex power architecture. To preserve maximum flexibility, internal fusing is not included however, to achieve maximum safety and system protection, always use an input line fuse. The safety agencies require a fast-acting fuse with a maximum rating of 6A (see Safety Considerations section). Based on the information provided in this data sheet on inrush energy and maximum dc input current, the same type of fuse with a lower rating can be used. Refer to the fuse manufacturers data sheet for further information. April 28, 2021 2012 General Electric Company. All rights reserved. Page 2
