Test method: Increase the output current until protection. When protection, it can not cause fire, smoke, electric shock and other dangerous phenomena. It can recover automatically after eliminating overpower.
Test method: Pin 1-3 of short circuit U3; Protection mode: constant voltage. It can not cause fire, smoke, electric shock and other dangerous phenomenon. It can return to normal after eliminating over voltage. Note: Do not use the external voltage to test.
Test method: The overcurrent point is the current value of the output current increasing until the output voltage falls out of the stable voltage accuracy range. When protection, it can not cause fire, smoke, electric shock and other dangerous phenomena. After eliminating overcurrent, it can automatically resume to normal.

Schematic diagram of output stripe and dynamic test:
Connect the power supply input to AC SOURCE, and the output is connected to the electronic load through the fixture plate. Testing separately with sampling line of 30cm± 2cm from the power output port. Power wires are selected insulated wire with corresponding diameter based on the output current
3. Derating must be performed at low voltage or high temperature. For details, see the derating curve.
4. Test conditions: Test voltage is 500VDC;The test is conducted at ambient temperature of 25℃ and relative humidity of 65%RH.
5. The power supply will be installed as a component in the final equipment, which still needs to meet EMC conditions. The criteria are as follows:
A: The performance of the power supply does not allow any degradation compared with the normal condition.
B: The performance of the power supply is allowed to decline, but any kind of reset or function interruption is not allowed.
C: Allow automatic reset of short-term function interruption, and do not allow long-term function interruption or manual reset.

5. Test conditions: Test voltage is 500VDC; Test conditions: Test at ambient temperature of 25C/65%RH.
6. Operation method of efficiency test:
Connect the power input to the AC SOURCE and the output to the electronic load. It is recommended to use 22# wires for the sampling line. For the power line, select the insulated wire with the corresponding diameter according to the output current. The input and output voltage measurement points select the ports of power input and output for measurement.
The key parameters of the switching power supply are calculated as follows:
1.Source regulation: After the heat engine stabilizes at the rated input voltage and rated load for 15 minutes, measure and record the output voltage V1, VO, and V2 at the lower limit of the input voltage, rated input voltage (Normal), and upper limit of the input voltage.
2.Load regulation: After the heat engine stabilizes at the rated input voltage and rated load of the switching power supply to be tested for 15 minutes, the input voltage is rated input voltage, and the output voltage is recorded as V1, Vo(normal) and V2 when the load is measured at full load, half load and no load respectively.
3.Temperature coefficient: The output voltage Vo (normal) of the switching power supply under rated input voltage and rated load is measured respectively at room temperature, and the output voltage V1 and V2 are measured respectively at the highest temperature and the lowest temperature.
△T1= maximum temperature -- room temperature;
△T2= room temperature - the lowest temperature
4.Voltage set-point accuracy: After the heat engine is stabilized for 15 minutes at the rated input voltage and rated load, a value Vx with the maximum absolute difference between the output voltage and the reference value Vo is measured when the load and input voltage are changed. The reference value VO is measured and recorded as vo when the input voltage is rated input voltage and the load is half loaded.
5.Startup time: under rated input and output conditions, the time from startup to rise to the lower limit of voltage regulator accuracy of output voltage.
6.Holding time: under rated input and output conditions, the time from shutdown to drop to the lower limit of output voltage set-point accuracy. When measuring, the output load is full off and the output end without external capacitance. When measuring shutdown holding time, it should be at 90 degrees phase to cut off the AC input power.
7.The cycle of the output dynamic load characteristic is 4ms, where T1:2mS;T2: 2mS. The current change rate di/dt is 1A/uS.
