Technical description
The DC/DC 2,5A (DC/DC25SU)
the voltage range of 18V÷28V DC at the output, adjusted with the V
(Pmax
= 60W). 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).
