NOTE | 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 pairwire terminated with a 0.1uf & 47uf parallel capacitor. 3. Tolerance: includes set up tolerance, line regulation and load regulation. 4. Length of set up time is measured at cold first start.Turning ON/OFF the power supply may lead to increse of the set up time. 5. The power supply is considered a component which will be installed into a final equipment. The final equipment must be reconfirmed that is still meets EMC directives.For guidance on how to perform these EMC test,pls refer to “EMI testing of component power supplies”(as available on http://www., ) 6. Installation clearances:40mm on top,20mm on the bottom,5mm on the left and right side are recommended when loaded permanently with full power.In case the adjacent devices is a heat source,15mm clearance is recommended. | |
