Isolated Buck-Boost 12V 3A 36W DC to DC Converter
The WEHO WH-D08401203 is a high-performance Isolated Buck-Boost converter, uniquely engineered to maintain a stable 12VDC output across an ultra-wide input range of 8V-40VDC. Its primary advantage is the automatic step-up/step-down capability, ensuring constant voltage even if the input source fluctuates below or above 12V. This 36W unit features galvanic isolation to eliminate ground loops and protect sensitive electronics from input-side noise. Built with a fully waterproof aluminum shell, it operates at 95% efficiency and includes auto-recovering over-current protection. It is the perfect isolated solution for mission-critical systems requiring absolute voltage stability.
