Remarks

 1. Ripple and noise measurement：Use twisted pair wire, the terminal is connected with 0.1uF and 47uF capacitors , measured under the condition of the oscilloscope bandwidth is 20MHz.

2. Voltage Accuracy: including setting error, load regulation; 

3. Standard configuration of structural size of plugs and wiring, it’s also can be customized.
