1. All parameters NOT specially mentioned are measured at 230VAC input, rated load and 25 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. Derating may be needed under low input voltages. Please check the derating curve for more details.
5. Touch current was measured from primary input to DC output.
6. with FGThe power supply is considered a component which will be installed into a final equipment. All the ( ) EMC test are beenClassⅠ
executed by mounting the unit on a mm* mm metal plate with 1mm of thickness. ( ) 360 360 The without FG EMC test is beenⅡClass
executed by mounting the unit on a 130mm 86.6mm metal plate with 1mm of thickness * . final equipment must be re-confirmed that it still
meets EMC directives. For guidance on how to perform these EMC tests, please refer to EMI testing of component power supplies.

Note: When the input voltage isAC 230V the model delivers EMI Class B for both conducted emission and radiated
emission for the power supply, When the input voltage is AC110V the model delivers EMI Class B for conducted
emission ,Class A for radiated emission for the power supply.
It delivers Class A for conduted emission and radiated emission, when configured into Class (without FG) system.Ⅱ
