12V to 28V 25A 700W DC to DC Converter
The WEHO WH-B122825 is a high-power DC-DC converter designed for systems requiring a significant power boost, delivering a potent 700W output. It converts a 12VDC input to a strong 28VDC, 25A supply with a high efficiency of 94%. Housed in a robust, fully sealed, and waterproof enclosure, it is built to perform reliably in even the most challenging environments. The unit includes intelligent overcurrent protection that automatically resets and requires a 120A fuse for complete short-circuit safety. With a proven reliability of over 100,000 hours, the WH-B122825 is an ideal solution for heavy-duty applications demanding both power and dependability.
