Selectable current LED drivers are power supplies for LEDs that offer users the capability to adjust the output current to their desired level, typically within a specified range. These drivers allow precise control of LED brightness by regulating the current flowing through the LED, making them ideal for applications where luminosity must be finely tuned.
Constant current LED drivers, on the other hand, maintain a steady output current regardless of variations in load or input voltage. This ensures consistent brightness levels and provides robust protection for LEDs against over-current and over-voltage conditions. Constant current LED drivers are frequently employed in applications demanding stable lighting performance, such as commercial, architectural, and retail lighting.
Both selectable current and constant current LED drivers come in various configurations, including standalone units, plug-in modules, and integrated solutions. The choice between the two driver types hinges on the specific application requirements, including the desired level of control and the need for unwavering lighting performance.
