Indoor LED Power Supply 12V 30A With No Fan For Hotel/Office Led Lighting Strips And Modules
Constant Current LED Drivers vs. Constant Voltage LED Drivers
Constant current and Constant voltage drivers are both viable options for a power supply for LED light sources, what differs is the way in which they deliver the power. LED drivers are the driving force that provides and regulates the necessary power to make sure the LEDs operate in a safe and consistent manner. Understanding the difference between the two types can:
-
Aid in properly powering LEDs
-
Avoid serious damages to your LED investment
