Adopted synchronous rectification technology, has high conversion efficiency(up to 96%), stable performance and low heat. With intelligent temperature, over-heat, short circuit and transient absorption high voltage protection, more safe to use. Uses Aluminum alloy shell and organic silica gel packaging technology, better to conduct heat, waterproof grade IP67. Easy to connect wires, Input: red(+) black(-), Output: yellow(+) black(-); please connect wires correctly, or it will be damaged. Compact design and small size, has wide application, car alarm, radio, interphone, motors, audio, navigator, monitor, LED car display, etc.
