Superior 3.3kW 144V DC Air-Cooled OBC for Low-Voltage Industrial EVs<\/span><\/strong><\/p>\n

The 3.3kW 144V DC Air-Cooled OBC is a heavy-duty charging solution designed for low-voltage industrial vehicles and small electric cars.<\/span><\/p>\n

The Ovartech CAD332DF-400A 3.3kW Air-Cooled OBC 144V DC for Low-Voltage Industrial EVs<\/strong> series is engineered for electric vehicle battery charging, meeting the strict demands for efficiency, robustness, and safety. With a wide AC input voltage range of 85~265V, the CAD332DF-400A is optimized for worldwide deployment, making it an ideal choice for global industrial fleet operators and small EV manufacturers. Its high-efficiency performance reduces energy consumption, delivering a more economical charging solution for daily operations.<\/span><\/p>\n

As a specialized low-voltage OBC, the CAD332DF-400A features an intelligent adaptive charging mode that automatically adjusts voltage output through CC\/CV (Constant Current\/Constant Voltage) protocols and initiates a safe cut-off once charging is complete, protecting battery health and extending service life. It also incorporates comprehensive multi-layer safety protections against short-circuit, over-voltage, over-current, over-temperature, and undercharging, ensuring stable and uninterrupted operation in all working conditions.<\/span><\/p>\n

The built-in CAN-bus interface enables seamless real-time communication with the vehicle\u2019s VCU (Vehicle Control Unit) via the BMS (Battery Management System). It accurately delivers critical data including charging flow status, interlock connection signals, and instant disconnection or error alerts, providing full visibility and control over the entire charging cycle for fleet management systems.<\/span><\/p>\n

The Ovartech CAD332DF-400A charger series is fully compliant with international industry standards SAE J1772 and IEC 61851, and holds an IP67 ingress protection rating. This rugged, air-cooled design withstands dust, water immersion, and the rigors of critical operating environments, ensuring long-lasting and reliable performance for all low-voltage industrial and small electric vehicle applications.<\/span><\/p>\n
