Remark

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

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

3. Accuracy: includes setting error, line regulation and load regulation.

4. Installation distance: When permanently loaded with full power, the recommended distance is 40mm at the top, 20mm at the bottom, and 5mm on both sides. If the adjacent device is a heat source, the recommended space distance is 15mm.

5. Output derating is required under low input voltage conditions. Please refer to the derating curve for details.

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

Guidelines for EMC test methods,

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