60V-72V to 12V 10A 120W DC to DC Converter

The WEHO WH-C60721210 is a highly efficient DC-DC buck converter designed to step down a high-voltage 60VDC or 72VDC input (ranging from 40V-90VDC) to a stable 12VDC output. Delivering 120W of power at 10A, it operates with a remarkable 95% efficiency, significantly reducing power loss and heat generation during operation. This compact unit is fully sealed and waterproof, ensuring reliable performance in demanding environments like electric vehicles and industrial automation. It features intelligent over-current protection that activates at 120% of the rated current and automatically recovers once the fault is cleared. With a precision 1% voltage tolerance and a long-term reliability of over 100,000 hours, it is a durable choice for high-voltage systems.
