The EHHD036A0F provides 3.3V nominal dc dc output voltage rated for 36A output current. The module incorporates GEs vast heritage for reliability and quality, while also using the dc latest in technology, and component and process standardization to achieve highly competitive cost. The open frame module construction, available in through-hole packaging, enable designers to develop cost and space efficient solutions. The module achieves typical full load efficiency greater than 90% at V =24V and V =48V . Standard features include remote On/Off, remote sense, output IN dc IN dc voltage adjustment, overvoltage, overcurrent and overtemperature protection. An optional heat plate allows for external standard, eighth-brick or quarter-brickheat sink attachment to achieve higher output current in high temperature applications. * Trademark of General Electric Company.

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 an integrated part of sophisticated power architectures. 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 15 A (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 21, 2021 2014 General Electric Company. All rights reserved. Page 2
