QMS DC-DC Series Data Sheet
Wide-Range Input, 70 to 82W Quarter-Brick Converters
Pre-bias Conditions
The QMS converters will start-up into a pre-bias voltage of
50% Vo NOM without damage.
Overvoltage Protection
The output overvoltage protection consists of a separate
control loop, independent of the primary control loop. This

secondary control loop has a higher voltage set point than
the primary loop. In a fault condition, the converter
enters a “Hiccup” mode of operation, and ensures that the
