High conversion efficiency: power converters use synchronous rectification technology to conversion efficiency. Has high conversion efficiency and stability. The conversion efficiency is as high as 94%. Low heat and stable performance. The delay time is less than 2S.Safety protection: These voltage converter embedded intelligent protection 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 connection of the 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 , hospital equipment, telecommunications, etc.It can be widely used in trucks, , taxi radios, car stereos, LCD , advertising screens, LED light , monitoring , motors, solar panels, electronic and DIY, etc.Material:Metalcolour:SilverPackage Contents:1 x TransformerOnly the above package content, other are not included.Note: Light and different displays may cause the color of the item in the a little different from the real thing.
