12V to 48V 20A 960W DC to DC Converter

The WEHO WH-B124820 is an industrial-grade DC-DC converter designed for extreme power applications, delivering a massive 960W output. It robustly converts a 12VDC input to a high-current 48VDC, 20A supply, operating at a high efficiency of 94%. This powerhouse is built to withstand the toughest conditions, housed in a fully sealed and waterproof chassis. A key feature is its exceptionally robust overcurrent protection, which activates at 200% of the rated current, ensuring maximum system resilience. For short-circuit safety, a 200A fuse is required. With a reliability of over 100,000 hours, it’s the definitive choice for heavy-duty, critical power systems.
