Pulsar DC/DC20SE Quick Start Manual

 The DC/DC voltage- step up / step down converter with
adjustable output voltage
 Example of use: increasing voltage from 9,5V to 12V DC or
lowering voltage from 16V to 9V DC
 The input voltage range: 9,5÷16V DC
 The output voltage range: 5÷15V DC
 The maximum load current 2A (24W)
 The PSU technical output indicating converter failure
triggered by:
 Short-circuit of the output
 Output overload
Example of use of the DC/DC20SE step up / step down converter with adjustable output voltage.
1. Technical 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 V
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 V
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).
