12V to 19V 10A 190W DC to DC Converter
The WEHO WH-B121910 is an exceptionally reliable DC-DC boost converter, engineered to convert a 12VDC source into a precise 19VDC output for specialized equipment. Delivering 190W of power at a constant 10A, it maintains a high conversion efficiency of 93% and a very low no-load power consumption of less than 0.1W. The unit is housed in a rugged aluminum chassis measuring $74\times74\times32mm$, utilizing natural cooling to maintain optimal operating temperatures even under full load. Designed for versatility, this fully waterproof and non-isolated module is built to withstand vibration and environmental stress. It includes advanced safety features like over-current protection with automatic recovery and requires a 15A fuse for short-circuit protection. With an MTBF of over 100,000 hours, it provides a “set and forget” solution for high-drain 19V systems.
