Reliabilityand Quality Control Impact aging 100% of the product is fully loaded and impacted for 4 hours under an environment of at least 40°C±5°C
Component derating Under the steady-state conditions of rated input and output, the stress of components will not exceed its maximum nominal value

1.All parameters not specifically mentioned are measured at 230VAC input, rated load and 25°C ambient temperature.

2.Ripple and noise test method: connect 0.1uF and 47uF capacitors in parallel at the terminal, and measure under 20MHZ bandwidth.

3.Ensure that the power supply is used under the rated parameters and environment.
