12V to 19V 15A 285W DC to DC Converter
The WEHO WH-B121915 is a high-capacity DC-DC boost converter designed for professional applications requiring a stable 19VDC output from a 12VDC input. It delivers a substantial 285W of power at 15A, maintaining an impressive 93% efficiency to keep thermal levels low. To handle higher power throughput, it features a larger $100\times80\times38mm$ aluminum heat-sink frame, which relies on natural convection cooling for silent and reliable operation. The unit is fully sealed and waterproof, making it the perfect choice for outdoor or mobile installations where durability is paramount. Safety is ensured through an auto-recovering over-current protection system that triggers when the load exceeds 120% of its rating. With a standby power draw of under 0.1W and a lifespan exceeding 100,000 hours, it is engineered for long-term, high-performance power delivery.
