## **DIMMING OPERATION** 

The PWM style output is a simple switching of supply ON/OFF at a rate so fast that the human eye cannot see led flickering. Duty cycle describes the proportion of time when output voltage is on relative to the entire period of time. It is expressed in percentage, 100% being fully on (maximal brightness) and a low duty cycle corresponding to lower brightness. 

Built-in 3 in 1 dimming function. The duty of the PWM style output can be adjusted through output cable by connecting a 0~10Vdc or 10V PWM signal or resistance between DIM+ and DIM-.

## ◎ **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 power supplies 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 power supplies, 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 www.meanwell.com/webnet/search/installationsearch.html for details.
