A reliable 48V to 12V 20A DCDC stepdown converter designed for golf carts and other 48V batterypowered vehicles. It delivers a stable 12V output across a wide input range (38V–56V) with efficiency to maximize your battery life. Efficient power conversion: 95% efficiency ensures minimal energy loss while supplying a steady 12V for accessories and electronics from a 48V system. Comprehensive protection: includes overcurrent, overvoltage, overtemperature shutdown, short circuit, and reverse polarity protection for safe operation in varied conditions. Waterproof and reliable: sealed enclosure and rugged construction support outdoor use and exposure to moisture, delivering consistent performance in demanding environments. Cooling and mounting: air convection cooling eliminates the need for extra fans or cooling gear, and a compact, mountable design allows straightforward installation in underseat, dash, or cargo areas of the cart or vehicle. Use scenarios Golf cart upgrade: power 12V accessories such as headlights, dash cams, radios, and USB charging from a 48V battery without risking the main pack. Utility or agricultural carts: run sensors, fans, or small electronics while preserving the 48V system for propulsion and other current loads. Outdoor or work vehicles: reliable 12V power in wet or dusty environments, enabling electronics in farm, marina, or maintenance carts.
