The EHHD010A0B [HAMMERHEAD*] Series, eighth-brick, low-height power modules are isolated dc-dc converters which provide a
single, precisely regulated output voltage over an ultra-wide input voltage range of 18-75Vdc. The EHHD010A0B provides 12Vdc
nominal output voltage rated for 10Adc output current. The module incorporates GEs vast heritage for reliability and quality, while
also using the latest in technology, and component and process standardization to achieve highly competitive cost. The open
frame module construction, available in both surface-mount and 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
IN dc IN dc
features include remote On/Off, remote sense, output voltage adjustment, overvoltage, overcurrent and over temperature
protection. An optional heat plate allows for external standard, eighth-brick or quarter-brick heat sink attachment to achieve
higher output current in high temperature applications.

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.

CAUTION: This power module is not internally fused. 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.
