Notes

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

2. Ripple and noise measurement method: Use a 12 "twisted pair with terminals 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. The power supply should be considered as a part of the internal components of the system, and electromagnetic compatibility related confirmation should be conducted in conjunction with the terminal equipment.

5. Installation distance: When permanently loaded with full power, it is recommended to have a top distance of 40mm and a bottom distance of about 20mm, with a distance of 5mm on both sides. If the adjacent equipment is a heat source, the recommended space distance is 15mm.

6. Under low input voltage, it is necessary to derate the output. Please refer to the derating curve for details.

7. When the altitude exceeds 2000 meters (6500 feet), the ambient temperature of the fanless model decreases in proportion every 3.5 ℃/1000m, while the ambient temperature of the fanned model decreases in proportion every 5 ℃/1000m.
