Test methods for switching power supply
1. withstand voltage testing
Definition: withstand the effective value of AC between specified terminals such as I/P-O/P, I/P-FG, O/P-FG, leakage current is generally allowed to be 10 MA and the time of 1 min.
1.2 Test conditions: Ta: 25 degrees Celsius; RH: indoor humidity.
1.3 Test circuit:
1.4 Description:
1.4.1 Voltage test is mainly to prevent electrical damage, through the input string of high voltage, affect the safety of users.
1.4.2 During the test, the voltage must be increased from 0V and reached the highest point within 1 minute.
1.4.3 Pay attention to the Timer setting of the tester when discharging, and switch the voltage back to 0V before OFF.
1.4.4 During the safety certification test, the transformer shall be separately measured. The temperature shall be 25 degrees Celsius, RH: 95 degrees Celsius, 48HR, and the transformer primary/secondary and primary /CORE shall be tested later.
1.4.5 Production line test time is 1 second.

2. Ripple noise (ripple noise voltage) testing
2.1 Definition:
Maximum (P-P) or effective value of the AC voltage component overlapped over DC output voltage.
2.2 Test conditions:
I/P: Nominal
O/P : Full Load
Ta: 25 ℃
2.3 Test circuit:
2.4 Test waveform:
2.5 Description:
2.5.1 The shorter the oscilloscope GND line, the better. The test line should be far away from the PUS.
2.5.2 Using a 1:1 Probe.
2.5.3 The Scope's BW is generally set at 20MHz, but it is better to set the BW to the maximum for the ripple noise of the current network products.
2.5.4 Noise and the use of the instrument, the environment is very different, so the test must indicate the test location.
2.5.5 Test ripple noise shall not exceed the original specification value +1%Vo.

3. Leakage current testing.
3.1 Definition:
Input the current flowing between the chassis (the chassis must be grounded).
3.2 Test conditions:
I/P: Vin Max) x 1.06 (TUV) / 60 hz
Vin max.(UL1012)/60Hz
O/P: No Load/Full Load
Ta: 25 ℃
3.3 Test circuit:
3.4 Description:
3.4.1 Both L and N need to be measured.
3.4.2 UL1012 R value is 1K5 and TUV R value is 2K/0. 15 uf.
3.4.3 Leakage current Specifications TUV: 3. 5 ma, UL1012:5 ma.
