| Note |
1. Unless otherwise specified, all specification parameters are measured at an input of 230VAC, rated load, and an ambient temperature of 25 ℃. 2. Ripple and noise measurement method: Use a 12 "twisted pair cable, 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 should be confirmed for electromagnetic compatibility 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, a bottom distance of 20mm, and a distance of 5mm on both sides. If the adjacent device is a heat source, the recommended spatial distance is 15mm. 6. Under low input voltage, the output needs to be reduced. 7. When the altitude exceeds 2000 meters (6500 feet), the ambient temperature of the fanless model decreases proportionally every 3.5 ℃/1000m, while the ambient temperature of the fanned model decreases proportionally every 5 ℃/1000m. |
