48V to 12V 80A 960W DC to DC Converter

The WEHO WH-C481280 is an ultra-high output DC-DC buck converter designed to transform a 48VDC source into a clean and stable 12VDC output. Delivering a massive 960W of power at 80A, it is a market leader for efficiency at 95%, minimizing heat generation even at extreme power levels. The unit is encased in a large 220x130x50mm aluminum housing that is fully sealed and waterproof, ensuring durability in challenging outdoor or industrial sites. It features intelligent over-current protection that activates at 120% of the rated current and short-circuit protection equivalent to a maximum current of 83A. Built for mission-critical systems, it boasts a lifespan exceeding 100,000 hours, making it the ultimate choice for high-current 12V needs in 48V battery environments.
