Isolated Buck-Boost 24V 20A 480W DC to DC Converter
The WEHO WH-D08401220 represents a high-power peak in our Isolated Buck-Boost series, transforming an 8V-40VDC input into a massive 240W output. Providing a steady 20A at 12VDC, it features integrated automatic voltage adjustment to maintain stability during severe source fluctuations. The complete galvanic isolation ensures the highest level of system safety by rejecting common-mode noise and preventing ground loops. Encased in a solid, fully waterproof aluminum housing, it maintains 88% efficiency and is designed for long-term reliability (MTBF > 100,000h). It is the ultimate choice for high-power, mission-critical isolated 12V systems.
