Remark

1. Unless otherwise specified, all specifications and parameters are measured at an input of 230VAC, rated load, and an ambient temperature of 25°C.

2. Ripple and noise measurement method: Use a 12" twisted pair, and the terminal should be connected in parallel with 0.1uf and 47uf capacitors, and measure at a bandwidth of 20MHZ.

3. Accuracy: including setting error, linear adjustment rate and load adjustment rate.

4. Installation distance: When permanently loaded with full power, the recommended distance is 40mm from the top, 20mm from the bottom, and 5mm from the left and right sides. If the adjacent device is a heat source, the recommended spacing is 15mm.

5. The output needs to be derated when the input voltage is low. Please refer to the derating curve for details.

6. The power supply is regarded as part of the components in the system and needs to be confirmed with electromagnetic compatibility in conjunction with the terminal equipment.

Guidance on EMC test methods,

7. When the altitude exceeds 2000 meters (6500 feet), the ambient temperature of the fanless model decreases at the rate of every 3.5℃/1000m, and the ambient temperature of the fan model decreases at the rate of every 5℃/1000m.
