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. Length of set up time is measured at cold first start. Turning ON/OFF the power supply may lead to increase of the setup time.
5. Derating may be needed under low input voltages. Please refer to the STATIC CHARACTERISTICS for more details.
6. The power supply shall be regarded as one component of the final system. The EMC performance will be affected by the complete system installation
and/or configuration, the final system manufacturers must re-verify overall EMC directive with the complete installation and/or configuration.
7. The ambient temperature derating of 3.5℃/1000m is needed for operating altitude greater than 2000m(6500ft).
8. The water protection level test for the IP68 rating is performed 1000mm below the surface of the water for 1 month.
9. Please refer to the warranty statement on MEAN WELL's website at http://www.meanwell.com
