24V to 12V 40A 480W DC to DC Converter

The WEHO WH-C241240 is a formidable DC-DC converter, delivering a massive 480W of power for the most demanding 12V systems. It steps down a 24VDC input to a powerful 12VDC, 40A output, all while maintaining an excellent 95% efficiency. This unit is built for tough jobs, featuring a robust, fully sealed, and waterproof housing and heavy-duty 12AWG wiring. Its enhanced safety features include a trip-point overcurrent protection at 150% load and require a 42A fuse for complete short-circuit protection. With a proven reliability of over 100,000 hours, it is the ultimate solution for high-current, critical applications.
