NOTE| 1. Al parameters NOT specially watered are meastrei at 230VAC input rated Iced and 25°C of amtient temperate.
2. Ripple & noise are neared at 20MHz of teniwiti by using a 12″ Misted pay/rare terminated with a 0.1ul& 47uf parallel capacitor.
3. Tolerance: imlutos set up taance. Ire regulation and load regulation
4. Dwatig may be needed under low iput voltage. Please check the static characteristics for more Maas.
5. 33% Cuty cycle mamun vain every 30 saccade, Average MN poser should not exceed the rated pear.
6. The poser suppty is ccrisklerei a component which MI be Metaled irto a RS equipment Al the EMC tests are been executed by mounting the unit on a 360mm*360mm metal plate wit 1mm cf thickness. The final equiprnent must be re- ccritmed that it still meets EMC directives. For guidance on how to perkan these EMC tests. please refer to “EMI testirg d ccrrponent pow swims.” (as amide on http://www.meanwell.com)
7. The ambient temperate deratig of 3.5°C /1000m with fatless models and of 5°C/1000m with fan models for operafrg allude higher than 2000m(6500ft).
