Protection Functions

• Short - circuit Protection: Protects the power supply and connected devices from damage in case of a short circuit.

• Overload Protection: Protects within the range of 110% - 140% of the rated output power. It adopts hiccup mode and recovers automatically after the fault condition is removed.

• Over - voltage Protection: Protects the load from being damaged by excessive output voltage. The protection range is about 4.62 - 5.46V. It adopts hiccup mode and recovers automatically after the fault condition is removed.

• Over - temperature Protection: Activates when the internal temperature of the power supply is too high, preventing damage to components. It adopts hiccup mode and recovers automatically after the fault condition is removed.

Other Features

• LED Indicator: There is an LED indicator for power - on, which allows users to easily check the working status of the power supply.

• Full - load Burn - in Test: 100% full - load burn - in test is carried out to ensure the reliability and stability of the product.

• Warranty: 3 - year warranty.

• Certifications: Complies with international safety regulations such as IEC / UL 62368 - 1, CE, CB, RCM.
