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. 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.

7. 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.

8. The water protection level test for the IP68 rating is performed 1000mm below the surface of the water for 1 month.

9. 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}.
