Description
The QHHD019A0B [HAMMERHEAD*] Series, quarter-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 QHHD019A0B provides 12Vdc nominal
output voltage rated for 19Adc 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, enable designers to develop cost and space efficient solutions. The module achieves typical full load efficiency greater
than 93% at VIN=24Vdc and VIN=48Vdc. Standard features include remote On/Off, remote sense, output voltage adjustment, overvoltage,
overcurrent and over temperature protection. An optional heat plate allows for external standard, 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 technical requirement. 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 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 25A (voltage rating
125Vac) in the ungrounded input lead. (Littelfuse Part #0456025, Surface Mount 456 Series - Nano 2® or equivalent, see Safety
