1. Technical description.
1.1. General description.
The converter is designed to supply devices requiring stabilized voltage of 12V DC. The maximum load current is
0,5A* (Pmax= 6W). The module does not feature galvanic isolation between input/output (Input-Output), and
operates on common "ground" (0V) potential. The inverter is protected against reverse polarity of the input voltage.
