1. Technical description
The step down
converter
DC/DC 3A
(
DC/DC30HV)
is used for step down the input voltage from the range between
28V÷60V
DC to the voltage range of 12
V÷24V DC at the output, adjusted with the
V
ADJ
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).
