The duty cycle of output current could drop down to 0% when dimming input is less than 6KΩ or less than 0.6VDC, or 10V PWM signal with duty cycle less than 6%. 

- ※ DALI Interface  (primary side; for DA/DA2-Type) ‧Apply DALI signal between DA+ and DA-. 

- ‧DALI protocol comprises 16 groups and 64 addresses. 

- ‧First step is fixed at 0.2% of output

## **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. 

- ‧For more information about installation, Please refer to : http://www.meanwell.com/manual.html for details.

Compliant Alternatives

We identify pin-to-pin, electrically equivalent substitutes that meet the same certifications (RoHS, AEC-Q100, REACH) as your original specification — validated against datasheets, not just part numbers. Often at a lower cost.
