48V to 12V 30A 360W DC to DC Converter

The WEHO WH-C481230 is a high-efficiency step-down buck converter designed to provide a stable 12VDC output from a 48VDC source. Delivering 360W at 30A, it operates with a superior 95% efficiency, making it a market leader for minimizing energy loss. This model is unique for its input low-voltage protection, which shuts off the output at ≤26VDC to prevent battery over-discharge and self-recovers at ≥29VDC. The fully waterproof $100\times80\times38mm$ aluminum enclosure provides excellent protection and utilizes natural cooling for maintenance-free operation. It features intelligent over-current protection and output short-circuit protection limited to 35A. With a reliability of over 100,000 hours, the WH-C481230 is the perfect choice for powering 12V accessories in 48V electric vehicles and industrial systems.
