Compact 36V/48V to 12V 40A 480W Step-Down Converter for DIY Power Supply

This high-reliability and high-efficiency DC-DC 48V step-down to 12V 40A 480W voltage transformer features a die-cast aluminum shell sealed with thermal conductive silicone to achieve natural heat dissipation. It is waterproof, dustproof, and shockproof, with built-in over-temperature, over-current, over-voltage, and output short-circuit protection, as well as auto-recovery when the device returns to normal operating conditions. Its compact structure makes it easy to install.

Kindly note the following: 1) The input voltage must be higher than the output voltage, as this is a step-down converter and does not have boost capability; 2) Do not reverse the input and output interfaces; 3) Prefer a stable DC power supply as the input, or filter it with a capacitor if using pulsed DC power from a generator.
