Protection type: Turn off the output voltage, after the temperature drops, re-energize to restore.
Over voltage protection Output voltage ≥120%-140%, turn off the output,after the abnormality is eliminated, re-energize to recover
Over load protection Load current ≥102%~110%, turn off the output, and automatically recover after the fault is eliminated.
Short circuit protection Protection type: It can be automatically restored after the fault is eliminated.

Reliability and 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 dc power supply is used under the rated parameters and environment.
