DESCRIPTION

The BR300-12S is a new generation isolated DC-DC converter that uses an

industry standard quarter-brick structure, and features high efficiency and

power density, operates from an input voltage range of 36 V to 75 V, provides

the rated output voltage of 12V and the maximum output current of 25A.
