DC/DC 5A module of converter
DC/DC50SD v.1.0/II
DC/DC 5A Step down DC/DC converter with adjustable output voltage
DESCRIPTION
VADJ
The step down converter DC/DC 5A (DC/DC50SD) is used for step down the input voltage from the range between
8V÷28V DC to the voltage range of 4,5V÷24V DC at the output, adjusted with the potentiometer. The maximum load
current is Imax=5A (Pmax = 60W). The 2V difference between the input (lowered) and output voltage is required for the
proper operation of the converter. 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
