DESCRIPTION
5 5 HV
2 60 12 24 VADJ
The step down converter DC/DC A (DC/DC 0 ) is used for step down the input voltage from the range
between 8V÷ V DC to the voltage range of V÷ V DC at the output, adjusted with the potentiometer.
The maximum load current is Imax=5A (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).

impedance), normal status: L level (0V)
Optical indication
- IN LED indicating DC power status
- AUX LED indicating DC supply status at the output
- PSU LED indicating failure - overload or short-
circuit in the AUX output
- red, normal status: is lit continuously
- green, normal status: is lit continuously
- red, normal status: does not lit, failure: is lit continuously
