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 start!2. When the input voltage is AC15-AC28V, the conversion efficiency of the module is 90%, 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 3.5A!3. 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%-90% maximum; when DC input, the input terminal is not divided into positive and negative poles!<br> .wang-edit-text{<br> font-family:'Arial' !important;<br> }<br> .wang-edit-text table {<br> border-top: 1px solid #000;<br> border-left: 1px solid #000;<br> }<br> .wang-edit-text table td,<br> .wang-edit-text table th {<br> border-bottom: 1px solid #000;<br> border-right: 1px solid #000;<br> padding: 3px 5px;<br> }<br> .wang-edit-text table th {<br> text-align: center;<br> }
