Technical description

The step down converter DC/DC 5A (DC/DC50HV) is used for step down the input voltage from the range between 28V÷60V
DC to the voltage range of 12V÷24V 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).
