NOTE

1. All parameters NOT specially mentioned are measured at 230VAC input, rated load and 25 °C  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.Constant current operation region is within 60% ~100% rated output voltage, and the output power must be more than 60% rated output power.This is the suitable operation region for LED related applications, but please reconfirm special electrical requirements for some specific system design.
5.Derating may be needed under low input voltages. Please check the static characteristics for more details.
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.
