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. Please see "AC input voltage drop vs. output current characteristics" table.

4. Constant current operation region is within 50% ~100% rated output voltage. This is the suitable operation region for LED related applications, but please

reconfirm special electrical requirements for some specific system design.

5. Direct connecting to LEDs is suggested, but is not suitable for using additional drivers.
