NOTE| 1. All parameters NOT specially mentioned are measured at 400VAC input, rated load and 25 C of ambient temperature.
2. Ripple & noise are measured at 20MHz of bandwidth by using a 12″ twisted pair-wire terminated with a 0.1uf & 47uf parallel capacitor.
3. Tolerance: includes set up tolerance, line regulation, and load regulation.
4. The power supply is considered a component which will be installed into a final equipment. The final equipment must be re-confirmed that it still meets EMC directives.
5. Dual phase operation: derating of 20% is required.
6. The ambient temperature derating of 3.5t /1000m with fanless models and of 5C/1000m with fan models for operating altitude higher than 2000m(6500ft)
