The QA1250E Series Smart Battery Charger is designed for reliable 24V, 48V and 72V battery charging in industrial vehicles, electric equipment, energy storage systems and smart power applications.
QA1250E Series Smart Battery Charger | 24V 30A / 48V 25A / 72V 15A
The QA1250E Series is a compact, high-efficiency smart battery charger family designed for 24V, 48V, and 72V battery systems. It combines a universal 100-240V AC input, programmable DC charging output, high power factor, high efficiency, active-fan cooling, and CAN BUS communication in one rugged charger platform.
The series includes three selectable models: QA1250E-24V30A for 24V systems, QA1250E-48V25A for 48V systems, and QA1250E-72V15A for 72V systems. According to the product parameter table, the output voltage ranges are 24-34V, 39-60V, and 60-88V respectively, with maximum output current up to 30A, 25A, and 15A depending on model and AC input condition.
Built with a die-cast aluminum enclosure and IP65 protection rating, the QA1250E Series is suitable for battery sheds, equipment enclosures, utility vehicles, marine shore-power setups, mobile work platforms, and other dusty or wet-exposure installations when proper cable sealing, strain relief, and drainage practices are followed. IP65 means dust-tight and protected against water jets under defined test conditions; it does not mean immersion-proof.
Each charger supports lead-acid, Li-ion, and LiFePO4 charging voltage presets by model. The 24V model supports typical charge targets of 29.4V for lead-acid, 29.4V for Li-ion, and 29.2V for LiFePO4. The 48V model supports 58.8V, 54.6V, and 58.4V respectively. The 72V model supports 88.2V, 84.0V, and 84.0V respectively.
With ≥93% efficiency, ≥0.99 power factor, 3-color LED status indication, and CAN BUS interface, the QA1250E Series is designed for system integrators, EV/utility vehicle builders, battery pack applications, and equipment users who need a compact charger with clear model selection and reliable charging performance.
