This series is a Quarter-Brick, wide-input intermediate bus
converter (IBC). Capable of operating from any input voltage in the
range 36 Vdc to 75 Vdc, this high efficiency isolated dc-dc
converter module generates a semi-regulated 12 V output and can
deliver up to 14 A. This series features a low profile open-frame
construction and has an industry standard quarter-brick footprint.
