An led lighting power supply is an electrical device which regulates the power to an LED or a string (or strings) of LEDs. An LED driver responds to the changing needs of the LED, or LED circuit, by providing a constant quantity of power to the LED  as its electrical properties change with temperature. An power supply for led is a self-contained power supply which has outputs that are matched to the electrical characteristics of the LED or LEDs. LED driver power supply may offer dimming by means of pulse width modulation circuits and may have more than one channel for separate control of different LEDs or LED arrays. The power level of the LED is maintained constant by the LED driver as the electrical properties change throughout the temperature increases and decreases seen by the LED or LEDs. Without the proper driver, the LED may become too hot and unstable, therefore causing poor performance or failure.

Our led display power supply are UL/cUL, ETL/cETL,FCC, CE, Rohs listed and Class 2. We offer vast collection of 100-277VAC/ 100-265VAC Dimmable and Non-Dimmable LED Drivers for use in all kinds of LED Lights. Drivers are also covered by 2-7 year manufacturer limited warranty. If you would like to know more details about LED POWER SUPPLY, Quanzhou Smarts Electronics  would like to help you. login https://www.smarts-electronics.com/ and http://www.smartselectronics.com/
