48V to 12V 50A 600W DC to DC Converter
The WEHO WH-C481250 is a heavy-duty DC-DC buck converter, specifically built to provide a powerful 600W output of 12VDC at 50A from a 48VDC input. It operates at an exceptionally efficient 95%, significantly reducing thermal stress and ensuring long-term durability. The fully sealed and waterproof $150\times127\times63mm$ aluminum chassis utilizes natural cooling to maintain a safe temperature rise of 45°C under load. This model features intelligent input low-voltage protection to safeguard your battery source from deep discharge. Safety is paramount, featuring auto-recovering over-current protection and specialized output short-circuit protection. Boasting a reliability of over 100,000 hours and a precision 1% voltage tolerance, the WH-C481250 is the ideal high-current solution for complex 48V to 12V power management.
