DESCRIPTION
The DC/DC 48V/2,5A (DC/DC48250) step up converter increasing the input voltage from the range between
18V÷28V DC to the voltage range of 48V DC at the output. The maximum load current is Imax=2,5A (Pmax =
120W). 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).
