High conversion efficiency: Our power converters use synchronous rectification technology to improve conversion efficiency. Has high conversion efficiency and stability. The conversion efficiency is as high as 94%. Low heat and stable performance. The start delay time is less than 2S. Safety protection: These voltage converter embedded intelligent protection chips provide 11 protection functions such as overcurrent protection, overheat protection, short circuit protection, high voltage protection, and overload protection. (Note: There is no reverse connection protection. Please pay attention to the correct connection of the positive and negative poles!) Waterproof module, water and electricity work experiment, load test for 60 minutes, there is no fault in the module. The transformer power supply has a service life of more than 100,000 hours. It is slim, small and easy to install. Wide range of applications: The waterproof housing makes the converter very suitable for a wide range of applications, including vehicles, security systems, hospital equipment, telecommunications, etc. It can be widely used in trucks, cars, taxi radios, car stereos, LCD , advertising screens, LED light bars, monitoring systems, motors, solar panels, electronic systems and DIY, etc. Material: Metal colour: Silver Package Contents: 3 x Transformer Only the above package content, other products are not included. Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
