The QHHD019A0B provides 12V nominal dc dc output voltage rated for 19A 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, enable designers to develop cost and space efficient solutions. The module achieves typical full load efficiency greater than 93% at V =24V and V =48V . Standard features include remote On/Off, remote sense, output voltage adjustment, overvoltage, IN dc IN dc 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. * 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 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 2 125Vac) in the ungrounded input lead.
