Highly integrated SMD components for high stability and reliability.IP67 waterproof and dustproof, easily adapt to various working environment.With overload or over-current or over temperature or 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 and electronic componentsInput voltage: AC 10-28VOutput voltage: DC12V0.25VOutput current: 3AOutput power: 36WContinuous working current: 2A or 3.5AConversion efficiency: 96 percent 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 percent , 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 percent -90 percent 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.
