1. All parameters NOT specially mentioned are measured at230VAC input, rated current and 25 _ of ambient temperature.
2. Please refer to “DRIVING METHODS OF LED MODULE”.
3. Ripple & noise are measured at 20MHz of bandwidth by using a 12" twisted pair-wire terminated with a 0.1uf & 47uf parallel capacitor.
4. Tolerance: includes set up tolerance, line regulation and load regulation.
5. De-rating is needed under low input voltages. Please refer to “STATIC CHARACTERISTIC’ sections for details.
6. Length of set up time is measured at first cold start. Turing ON/OFF the driver may lead to increase of the set up time.
7. The driver 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. This seriesmeets thetypical life expectancy of50000 hours of operation when Tcase, particularly(tc)point (orTMP, perDLC), is about 75
