48V to 12V 60A 720W DC to DC Converter
The WEHO WH-C481260 is the high-capacity leader of our 48V to 12V step-down series, delivering an impressive 720W and 60A of continuous current. It converts a 48VDC input to a stable 12VDC output with an industry-leading 95% efficiency. Housed in a robust $150\times127\times63mm$ aluminum enclosure, it is fully sealed and waterproof, ensuring reliable power delivery in even the harshest environmental conditions. The converter includes advanced input low-voltage protection to protect the primary battery and features over-current protection that automatically recovers once conditions stabilize. With a standby power draw of less than 4W and a precision 1% voltage tolerance, it provides exceptionally clean and stable power. Boasting a reliability of over 100,000 hours, the WH-C481260 is the ultimate high-power buck converter for professional system integration.
