Description
The EHHD024A0A [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 18-75V
dc
. The EHHD024A0A provides 5V
dc
nominal output voltage rated for 24A
dc
output current. The module incorporates GE’s 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 91% at V

. Standard
features include remote On/Off, remote sense, output 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.
