How to check the switching power supply leakage current
Need to use pressure tester. Through the pressure tester measured leakage current value, minus the switching power supply to the ground capacitance of the current value, is the switching power supply leakage current. Or disconnect the switching power supply to the ground capacitor, the voltage tester measured by the leakage current value is the need to measure the leakage current value.
60601 or 60950, third line class I or two line class II, but no matter how! General market has a special test switching power leakage current tester, you can check the Internet, because I have used before But the manufacturer model forgot.
Insulation tester (pressure value)
Vin to GND
Vout to GND
Vin tested against Vout separately
Test the voltage transferred to your power corresponding to the standard on the line.
You will see the leakage current in the insulation tester display value.
