The Orion XS is the most compact, high power DC-DC charger available, delivering up to 98.5 % charging efficiency. Its robust, fan less design stays cool while maintaining full rated output, even in hot, cramped compartments. Â Input current can be precisely limited to prevent alternator overload. Charging voltage is fully configurable to match lithium, AGM, Gel, and other battery chemistries. For mixed-voltage systems, the Orion XS 1400 also provides 12V to 24V or 24V to 12V conversion. The Orion XS uses a re-engineered aluminium circuit board that also acts as a heat sink, combined with more efficient components to reduce power loss. Its fan less design delivers full output 700W for 12|12 models or 1,400W for the 1400 up to 40°C (104°F) before any thermal derating occurs.
