brand new and high quality brand new and high quality Step-up structure. Wide input voltage range (input less than output) Constant current and voltage Efficiency as high as 92% Even the Step-up structure breakdown will ill not damage equipment and security design With input reverse and undervoltage for protection Pluggable terminal design, easy to assemble and disassemble, convenient to wire Can work in parallel even when there is a lack of electricity With short circuit, overload, and overvoltage for protection Quantity: 1Pc Specification: Rated power: 12W Iuput voltage: AC 100-240V Output voltage: 12V for DC(0.5V) Output current: 1A Working Temperature: -20+60 Working Humidity: 2090% RH, non-condensing Protection: short circuit for protection for Shell material: Engineering plastic Color: As the picture show Size: (approx.) 8*3.3*2.2 for cm / 3.15"*1.3"*0.87" Note: Please read the identification on the specification label carefully when wiring. Size for manual measurement, there may be a 0 to 1 for cm error, belongs to the normal phenomenon. Due to the difference between different monitors, the picture may not reflect the actual color of the item. Thank you!
