12V to 19V 5A 95W DC to DC Converter
The WEHO WH-B121905 is a highly efficient DC-DC boost converter, specifically designed to step up a 12VDC input (ranging from 9V-16VDC) to a stable and regulated 24VDC output. Delivering 120W of power at 5A, it operates with a remarkable 93% efficiency, significantly reducing power loss and minimizing heat generation during heavy-duty tasks. This compact unit is fully sealed and waterproof, ensuring reliable performance in the most demanding environments, from industrial sites to marine applications. It features intelligent, auto-recovering over-current protection that activates at 120% of the rated current and requires a 15A fuse for input short-circuit safety. With a long-term reliability of over 100,000 hours, the WH-B121905 is a durable choice where consistent 24V power is essential.
