1. Technical description The DC/DC 2,5A (DC/DC25SU) step up converter increasing the input voltage from the range between 9,5V÷16V DC to the voltage range of 18V÷28V DC at the output, adjusted with the VADJ potentiometer. The maximum load current is Imax=2,5A (Pmax = 60W). 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). 1.1.

2.2. Installation procedure. 1. Mount the enclosure (cabinet, etc.) and lead cables through cable glands. 2. Mount the DC/DC converter with adhesive tape or mounting screws. 3. Supply DC voltage to the + IN, -IN terminals with correct polarization. 4. Switch on the DC voltage. 5. Use the jumper to set the required voltage range and adjust the required output voltage with the VADJ potentiometer. Default setting: 24V. 6. Switch off the DC voltage. 7.
