The Xantrex XHR120 is a 12V DC battery charger engineered for marine and RV applications requiring reliable, efficient charging across multiple battery chemistries. The unit employs a three-stage charging algorithm—Bulk, Absorption, and Float—to optimize charge rates while protecting battery longevity. Its auto-ranging AC input accepts 80 to 265 Vac (45 to 65 Hz) and delivers nominal 12V DC output with a power factor exceeding 0.98 at full charge rate. The charger supports lead-acid battery types including Flooded, AGM, and Gel, with capability to initiate charging from fully discharged (0V) battery states. Thermal-controlled dual-fan cooling maintains safe operating temperatures across demanding environments. Construction withstands harsh marine and mobile conditions, incorporating comprehensive protection mechanisms for both charger and battery systems. The unit functions reliably across operating temperatures from -20°C to 60°C (with output derating above 40°C) and humidity from 5% to 95% RH non-condensing.
