| Charge current | 2.5 ADocumented claim ConditionsContinuous output current at nominal output voltage and 25 °C, printed one figure per column; 2,5 A is the 24/48-2,5 (120 W) column. The datasheet says this converter is not intended for battery charging (it recommends the Orion-Tr Smart for that); the figure is its continuous output current. Location: Isolated converters 110 – 120 W table (PDF page 1), 24/48-2,5 (120 W) column Continuous output current at nominal output voltage and 25 °C, printed one figure per column; 2,5 A is the 24/48-2,5 (120 W) column. The datasheet says this converter is not intended for battery charging (it recommends the Orion-Tr Smart for that); the figure is its continuous output current.
