Features Multiple Protection Functions: The step down converter has built-in multiple protections, including overvoltage, overcurrent, overheating and short circuit protections. Selected Components: AC12V to DC12V power converter adopts precision manufacturing technology and sensitive components. It has a stable and reliable structure and is an integrated SMD component integrated with high stability and reliability. IP67 Waterproof And Dustproof: The power converter has the characteristics of IP67 waterproof and dustproof, and it is easy to adapt to various working environments and strong practicality. Low Heat Generation: The shell of the power converter module is made of flame-retardant plastic material, which has low heat generation during use and can effectively play a protective role. Scope of Application: Waterproof power converter is suitable for using scenes such as car screens, monitoring cameras, fan, pumps, motors, routers and other scenarios. Specification: Input voltage: AC 10-28V Output voltage: DC12V±0.25V Output current: 1A/2A/3A/5A (Optional) Output power: 12W/24W/36W/60W Continuous working current: 2A/3.5A Conversion efficiency: ≥96% Protection level: IP67 Working temperature: -20~80℃   Package list: 1 x Converter  Note: 1. When the input voltage is AC10-14V, the output current is less than 1A; when the output voltage is 12V, it is not recommended to output with load at this time, because the conversion efficiency is low at this time; the output 12V after loading will cause the output to be unstable and big output fluctuation.The load is too big to start! 2. When the input voltage is AC15-AC28V, the conversion efficiency of the module is ≥90%, and the output voltage can maintain DC12V±0.25V. At this time, the 3A module can support long-term work within 2A, and the 5A module can support long-term work within 3.5A! 3. The input voltage also supports DC input, and the DC input range is DC16-36V. DC input conversion efficiency is low, the conversion efficiency is 83%-90% maximum; when DC input, the input terminal is not divided into positive and negative poles! Package List
