四、模块电源应用方法1.输出电压调节对有TRIM或ADJ(可调节)输出引脚的模块电源产品,可通过电位器对输出电压进行调节,一般调节范围为±10%。对TRIM输出引脚,将电位器的中心与TRIM相连,其它两端分别接+S、-S。没有+S、-S时,将两端分别接到相应主电路的输出正负极,然后调节电位器即可。电位器的阻值,一般选用5～10kΩ比较合适。如图3所示。
Fourth, the module power supply application methods 1. Output voltage regulation For TRIM or ADJ (adjustable) output pin module power supply products, the output voltage through the potentiometer to adjust the general adjustment range of ± 10%. TRIM output pin, the center of the potentiometer and TRIM connected to the other ends were connected to + S, -S. Without + S, -S, the two ends are respectively connected to the output of the corresponding main circuit positive and negative, and then adjust the potentiometer can be. Potentiometer resistance, the general selection of 5 ~ 10kΩ more appropriate. As shown in Figure 3.
