DC-DC Step Down Voltage Converter Waterproof 30A 360W (36~60Vdc to Fixed Output 12Vdc/30A) SKU#DC112

36V/48 V → 12 V, 30 A, 360 W Waterproof DC-DC Converter (IP68)

Effortlessly step down voltage with this robust, high-efficiency converter. It delivers a stable 12 V output at up to 30 A (360 W), from input sources ranging 30–60 V (up to 90 V on certain variants). Built for demanding environments, the die-cast aluminum housing with epoxy sealing offers IP68 protection and ensures reliable thermal performance via natural convection.

Key features include advanced protection circuits—against over-current, short-circuits, over-voltage, and overheating. It also offers superb performance with ripple as low as 50 mV and regulation better than ±0.2%. Compact and designed to last, it's ideal for applications like golf carts, EVs, marine systems, lighting arrays, and more.
