1. Technical description.
1.1. General description.
The DCDC converter is used for powering devices that require stabilized voltage of 12 V DC. The maximum current
load is 1,5 A* (Pmax= 18W). This module does not have galvanic insulation between the input and output (IN-AUX), and
operates on a common ground potential. The unit is protected against short circuit, overload and against reverse input
voltage polarity.
