NOTE	1. All parameters NOT specially mentioned are measured at 220VAC 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. Please refer to OLP characteristics.
	5. Derating may be needed under low input voltages. Please check the derating curve for more details.
	6. This is the maximum possible output current and power, over load protection may be activated slightly below this level to comply with the
	requirement of  EN61547:1995+A 1:2000 class 2
	7. 1years warranty is guaranteed for operating ambient temperature no higher than 68 .
	8. Constant current operation region is within 50% ~100% rated output voltage. This is the suitable operation region for LED related applications.
