Note           1.All parameters not specially mentioned are measured at 230V AC input,rated load and 25°C 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 first cold start.Turning ON/OFF the power supply may lead to increase of the setup time.

5.Derating may be needed under low input voltage.Please check the static characteristics for more details.

6.THD<25%at 277VAC,full load.

7.The unit might not be suitable for lighting applications in EU countries.Please check with your local authorities for the possible

use of the unit.

8.EMI performance will be affected by the installation of system,the final equipment manufacturers must re-qualify EMI Directive on the

complete installation again.

9.Suitable for indoor use or outdoor use without direct sunlight exposure.
