Author : Abb Published Time : 2018-11-12

ABB Embedded Power QSxW050A0B DC/DC Converter Power Modules are a new generation of modules designed to support intermediate bus applications where multiple low voltages are generated. These power modules are available in two versions 'D' with a digital communications interface and 'V' with the standard control interface. The QSxW050A0B DC/DC modules operate from 36V_DC to 75V_DC input voltage range and provide up to 50A output current at output voltages from 9.6V_DC to 12V_DC. These modules also provide 600W output power from output voltages of 12.1V_DC to 13.2V_DC in a DOSA standard quarter brick. The QSxW050A0B Barracuda III series power modules operate at -40°C to 85°C temperature range. Features include a base plate, output-voltage trim, remote sense, on/off control, input under- and over-voltage lockout, power good signal, and PMBus interface.
