R1/R2 are voltage trimming resistors. If the voltage is too high or too low, weld the R1/R2 resistor to adjust the output voltage.Adjustment range ±10%

If you need to increase the output voltage, please solder the R1 resistor
R1(Ω)= 25000/(Vout-12V)-5110

If you need to reduce the output voltage, please solder the R2 resistor
R2(Ω)= (Vout-2.5)/(12-Vout)*10000-5110
