1 All paramenters 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 0.1 uf & 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-confirmend that it still meets EMC directives
5 Installation clearances 40mm on top, 20mm on the bottom, 5mm on the left and right side are recommended when loaded permanaentyly with full power . in case the adjacent device is a heart source, 15mm clearance is recommended.
6 Derating may be needed under low input voltage. Please check the derating curve for more details |
