Functions: Highly integrated SMD components for high stability and reliability.<br> Fireproof plastic housing, safe and reliable.<br> IP67 waterproof and dustproof, easily adapts to different working conditions.<br> With overvoltage, overcurrent and short circuit protection.<br> Suitable for car screen, surveillance camera, fan, water pump, motor, router, etc.<br> Specification: Input Voltage: AC 10-28V<br> Output voltage: DC12V0,25V<br> Output current: 1A/2A/3A/5A (optional)<br> Output power: 12W/24W/36W/60W<br> Continuous operating current: 2A/3,5A<br> Conversion efficiency: 96%<br> Degree of protection: IP67<br> Operating temperature: -2080<br> List of packages: 1 x Converter<br> When the input voltage is AC10-14V, the output current is less than 1A; when the output voltage is 12V, it is not recommended at this time of output with load, because the conversion efficiency is low at this time; 12V output after loading will cause output instability and large power fluctuations. The load is too heavy to start!<br> When the input voltage is AC15-AC28V, the module conversion efficiency is 90%, and the output voltage can maintain DC12V 0,25V. At the moment, the 3A module can support long-term operation within 2A, and the 5A module can support long-term operation within 3,5A!<br> Input voltage also supports DC input, and the DC input range is DC16-36V. The input conversion efficiency of DC is low, the conversion efficiency is up to 83%-90%; when the input DC, 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.
