1. Technical description.
1.1. General description.
The DCDC converter is used for powering devices that require stabilized voltage of
12V DC.
The maximum current
load is
1.5A
*
(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.
