1. All parameters NOT specially mentioned are measured at 230VAC input, rated current and 25 of ambient temperature.
NOTE 2. De-rating may be needed under low input voltages. Please refer to “STATIC CHARACTERISTIC” sections for details. 3. Length of set up time is measured at first cold start. Turning ON/OFF the driver may lead to increase of the set up time.
4. 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.
(as available on https://www.meanwell.com//Upload/PDF/EMI_statement_en.pdf) 5. This series meets the typical life expectancy of >50,000 hours of operation when Tcase, particularly tc point (or TMP, per DLC), is about 75or less.
6. Please refer to the warranty statement on MEAN WELL’s website at http://www.meanwell.com 7. The ambient temperature derating of 3.5/1000m with fanless models and of 5/1000m with fan models for operating altitude higher than 2000m(6500ft).
8. For any application note and IP water proof function installation caution, please refer our user manual before using.
https://www.meanwell.com/Upload/PDF/LED_EN.pdf
9. Based on IEC 62386-101/102 DALI power on timing and interruption regulations, the set up time needs to test with a DALI controller which can support for DALI power on function, otherwise the set up time will be higher than 0.5 second for DA type.

Cautions Before commencing any installation or maintenance work, please disconnect the power supply from the utility. Ensure
that it cannot be re-connected inadvertently! Keep proper ventilation around the unit and do not stack any object on it. Also a 10-15 cm clearance must be kept when
the adjacent device is a heat source. Mounting orientations other than standard orientation or operate under high ambient temperature may increase the
internal component temperature and will require a de-rating in output current. Current rating of an approved primary /secondary cable should be greater than or equal to that of the unit. Please refer
to its specification. For LED drivers with waterproof connectors, verify that the linkage between the unit and the lighting fixture is
tight so that water cannot intrude into the system. For dimmable LED drivers, make sure that your dimming controller is capable of driving these units.PWM series
require 0.15mA each unit. Tc max. is identified on the product label. Please make sure that temperature of Tc point will not exceed limit. DO NOT connect “DIM- to -V”. Suitable for indoor use or outdoor use without direct sunlight exposure. Please avoid immerse in the water over 30
minutes. 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.
