1. Technical description

The step-down DC/DC converter module DC/DC-1.0A (DCDC10) is used for powering devices that require
stabilized voltage in the range of 4,5÷19V DC. The maximum current load is 1.0 A (Pmax= 12W). This module does
not have galvanic insulation between the input and output (IN-AUX), and operates on a common ground potential (IN
and AUX terminals are connected galvanically = common terminal).
