DESCRIPTION
VADJ
VADJ
The DC/DC 3A (DC/DC30SE) voltage- step up / step down converter is used for maintaining a constant output voltage in the
range between 5÷15V DC, adjusted with the potentiometer, regardless of the input voltage fluctuations in the range of 9,5V
÷ 16V. When the input voltage at the output is lower than needed, the converter increases it to the set value. When the input
voltage at the output is higher than needed, the converter lowers it to the needed value set by the potentiometer. The
maximum load current is Imax=3A (Pmax=36W). The module does not feature galvanic isolation between input/output (IN-
AUX) and operates on common "ground" (0V) potential (IN- and AUX- terminals are galvanically connected = common
terminal).
