DC/DC 2A module of converter switching
DC/DC20SE v.1.0/II
DC/DC 2A Step up/step down DC/DC converter with adjustable output voltage

DESCRIPTION
The DC/DC 2A (DC/DC20SE) voltage- step up / step down converter is used for maintaining a constant output voltage
in the range between 5÷15V DC, adjusted with the VADJ

potentiometer, regardless of the input voltage fluctuations in the
range of 9,5V ÷ 16V. When the input voltage at the output is lower than needed, the converter increases it to the set value.
When the input voltage at the output is higher than needed, the converter lowers it to the needed value set by the
potentiometer The maximum load current is Imax=2A (Pmax = 24W). 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).

circuit in the AUX output
- OC type, 50mA max. Failure status: hi-Z state (high
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
