What you Need to Know About Trimming the Output Voltage of a Power Supply

Click image to enlarge

Figure 1: Power supply output voltage is trimmed so that power supply voltage = desired load voltage + total conductor impedance voltage drop

What is Trimming and How is it Used? Trimming the output voltage of a power supply simply means adjusting the voltage by a small amount. By convention, the term trimming is used for applications where the power supply has a specified nominal output voltage and the user is able to change the output voltage
