AC 10-28V to DC 12V AC DC Converter Power Supply Module Features: 1. Highly integrated SMD components for high stability and reliability. 2. Fireproof plastic housing, safe and reliable. 3. IP67 waterproof and dustproof, easy to adapt to different working conditions. 4. With overvoltage, overcurrent, short circuit protection. 5. Suitable for car screen, surveillance camera, fan, water pump, engine, router etc. 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: ge; 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; 12V output after charging will cause the output to be unstable and large output fluctuation. The load is too heavy to start!2. When the input voltage is AC15-AC28V, the conversion efficiency of the module is ge; 90%, and the output voltage can maintain DC12V 0.25V. At this time, the 3A module can support long-term operation within 2A, and the 5A module can support long-term operation within 3.5A!3. The input voltage also supports DC input, and the DC input is DC16-36V. DC input conversion efficiency is low, conversion efficiency is 83%-90% maximum; When DC input, the input terminal is not divided into positive and negative poles!<br> Note: Due to the light and screen setting difference, the item's color may be slightly different from the pictures. Please allow slight dimension difference due to different manual measurement. Sold by-Minnanxin
