PROTECTION
|
Overtemperature
|
Protection type: Turn off the output voltage, after the temperature drops, re-energize to restore.
|
|
Over load protection
|
Shut down the output when current load ≥110%~150%, auto recovers.
|
|
Short circuit protection
|
Protection type: It can be automatically restored after the fault is eliminated.

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
|
|
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 power supply is used under the rated parameters and environment.
