| Charge current | 8.5 ADocumented claim ConditionsContinuous output current at nominal output voltage and 40 °C, printed one figure per column; 8,5 A is the 24/48-8,5 (400 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 360 - 400 Watt table (PDF page 2), 24/48-8,5 (400 W) column Continuous output current at nominal output voltage and 40 °C, printed one figure per column; 8,5 A is the 24/48-8,5 (400 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.
