| DIMENSION | 22.5*90*100mm (W*H*D) |
| NOTE | 1.All parameters NOT specially mentioned are measured at 230VAC 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 0.1 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-confirmed that it still meets EMC directives.
5.Length of set up time is measured at cold first start. Turning ON/OFF the power supply may lead to increase of the set up time. |
