Notices：
- All parameters NOT specially mentioned are measured at 230Vac input, rated load and 25℃ of ambient temperature.
- Ripple & noise are measured at 20MHz bandwidth using a 12-inch twisted pair-wire terminated with a 0.1μF & 47μF parallel capacitor.
- Tolerance includes set up tolerance, line regulation and load regulation.
- Derating may be required under low input voltages. Please refer to the static characteristic section for details.
- The power supply is considered a component installed into final equipment. EMC tests were executed by mounting the unit on a 360mm*360mm metal plate with 1mm thickness. The final equipment must be re-confirmed to meet EMC directives.
- The ambient temperature derating is 3.5℃/1000m with fanless models and 5℃/1000m with fan models above 2000m (6500ft).
