Waterproof Volt Converter Ac 10-28v To Dc 12v Buck Converter Ac-dc Power Module(3a) FG05 Highly integrated SMD components for high stability and reliability.IP67 waterproof and dustproof, easily adapt to various working environment.With overload/over-current/over temperature/short circuit protection, and it can work in normal condition when restoredThe fire retardant plastic casing, safe and reliable; The whole filling and sealing waterproof ing designSuitable for car screen, monitor camera, fan, water pump, motor, router, etc.Specification:Colour: BlackMaterial: ABS + electronic componentsInput voltage: AC 10-28VOutput voltage: DC12V0.25VOutput current: 3AOutput power: 36WContinuous working current: 2A/3.5AConversion efficiency: 96%Protection level: IP67Working temperature: -20~80Note: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 start2. When the input voltage is AC15-AC28V, the conversion efficiency of the module is 90%, and the output voltage can maintain DC12V0.25V. At this time, the 3A module can support long-term work within 2A, and the 5A module can support long-term work within 3.5A3. 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 polesPackage Contents:1 x ConverterOnly the above package content, other products are not included.Note: Light 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.
