PROTECTION

Overtemperature

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

NOTE

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.
