Wide Input 12V/24V to 5V 40A 200W DC to DC Converter

The WEHO WH-C12240540 is a robust DC-DC buck converter engineered to deliver 200W of power at 40A from a wide 9V-32VDC input. Converting to a precise 5VDC output, it features an efficient 94% conversion rate, significantly reducing thermal levels during operation. This module is housed in a $100\times80\times38mm$ aluminum chassis that is fully sealed and waterproof, ensuring reliability in industrial or automotive environments. Safety is prioritized with an auto-recovering over-current protection system and dedicated short-circuit safeguards. With a precision 1% voltage tolerance and a long-term reliability of over 100,000 hours, it is a premier choice for high-power 5V needs across diverse voltage infrastructures.
