The QSD(V)W050A0B series operate from an input voltage range of 36 to 75V and provide up to dc 50A output current at output voltages from 9.6V to 12V , and 600W output power from output voltages of 12.1V to 13.2V in a DOSA dc dc dc dc standard quarter brick. Two versions are offered, D with a digital communications interface and V with the standard control interface. These converters incorporate digital control, synchronous rectification technology, a fully regulated control topology, and innovative packaging techniques to achieve efficiency of 96% peak at 12V output. This leads to lower power dissipation such that for many applications a heat sink dc is not required. Standard features include a base plate, output-voltage trim, remote sense, on/off control, output over-current and over-voltage protection, over-temperature protection, input under- and over-voltage lockout, power good signal and PMBus interface. The output is fully isolated from the input, allowing versatile polarity and grounding connections. Built-in filtering for both input and output minimizes the need for external filtering. * Trademark of General Electric Company PMBus name and logo are registered trademarks of SMIF, Inc.

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 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 architecture, including hot-plug with no external inrush limiting. 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 25 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 30, 2021 2020 ABB. All rights reserved. Page 2
