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 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 static characteristics for more details.
5.  A type only.
6.  Safety and EMC design refer to BS EN/EN60598-1, CNS15233, GB7000.1, FCC part18.
7.  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.
8.  The power supply is considered as a component that will be operated in combination with final equipment. Since EMC performance will be affected by the complete installation, the final equipment manufacturers must re-qualify EMC Directive on the complete installation again.
9.  The water protection level test for the IP68 rating is performed 1000mm below the surface of the water for 1 month.
10.  The ambient temperature derating of 3.5℃/1000m with fanless models and of 5℃/1000m with fan models for operating altitude higher than 2000m(6500ft).
