Voltage Settings:

     There are A and B zero ohm  resistors on the front side of the board. The output voltage is set by connecting the resistors as in the table we show below and as shown on the back of the board. Since the A and B resistors come soldered from the factory, the output voltage operates as 12V. For the other voltages, 1 or 2 of the resistors must be removed according to the table. If you heat the pads with a soldering iron at high temperature for a long time ( 3-5sec ), the pads may separate from the pcb. In this case you may not be able to restore the previous condition. If you are going to perform soldering, it is important to work with quality material at the correct temperature for the minimum duration.
