12V to 19V 20A 380W DC to DC Converter
The WEHO WH-B121920 represents the high-power peak of our 19V step-up series, transforming a 12VDC input into a massive 380W output. Providing a steady 20A at 19VDC, it is the ultimate solution for powering heavy multi-device arrays or high-intensity mobile systems. This module operates with 93% efficiency and features an exceptionally clean output with a 1.5% voltage tolerance. Built for the toughest environments, it is fully sealed, waterproof, and encased in a solid $100\times80\times38mm$ aluminum housing. The design prioritizes system health with intelligent over-current protection that automatically restores operation once electrical faults are removed. Boasting a reliability rating of over 100,000 hours, the WH-B121920 is the premier choice for mission-critical 19V power where efficiency and ruggedness cannot be compromised.
