48V to 12V 40A 480W DC to DC Converter
The WEHO WH-C481240 is a rugged and versatile DC-DC buck converter, designed to step down 48VDC (30V-60V range) to a regulated 12VDC output. Delivering 480W of power at 40A, it boasts a high 95% efficiency rating and a low no-load consumption of less than 4W. The unit’s compact $118\times80\times28mm$ profile allows for installation in shallow spaces without sacrificing performance. It is equipped with input low-voltage protection (shutdown at ≤26V, recovery at ≥29V) and is fully sealed and waterproof for all-weather reliability. Advanced circuitry ensures a tight 1% voltage tolerance and 3% load regulation. With over-current protection and a reliability rating of over 100,000 hours, the WH-C481240 provides consistent, high-capacity power for demanding 12V loads in 48V battery environments.
