When the input voltage is AC 10-14V, 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 make the output unstable and cause large output fluctuations. The load is too heavy to start!2. When the input voltage is AC15-AC28V, the conversion efficiency of the module is ≥90%, and the output voltage can maintain DC12V ± 0.25V.Currently, the 3A module can handle continuous operation up to 2A, and the 5A module can handle continuous operation up to 3.5A!3.The input voltage also supports DC input, and the DC input range is 16 to 36V DC.The DC input conversion efficiency is low, with a maximum conversion efficiency of 83% to 90%; during DC input, the input terminal is not divided into positive and negative poles!
