*In order to extend the service life, it is recommended to leave 30% more allowance when loading. For example, if the equipment needs 100W power, please choose the power supply over 130W.

*Ripple&noise are measured at 20MHz of bandwidth by using a 12’’ twisted pair-wire terminated with a 0.1uf & 47uf parallel capacitor.

*All parameters NOT specially mentioned are measured at 230VAC input,rated load and 25℃ of ambient temperature。

*the auxiliary heat dissipation of aluminum plate with an area of 400 * 400 * 3mm must be used when full load working.

*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.All our EMC tests are carried out by mounting samples on metal plates.
