Selectable Current, Constant Current LED Drivers
Selectable current LED drivers are LED power supplies that allow the user to adjust the output current to a desired level, usually within a specified range. This type of driver provides the ability to fine-tune the brightness of LED lights by controlling the amount of current flowing through the LED. The ability to control the current is particularly important in applications where the LED luminosity needs to be carefully regulated.
Constant current LED drivers, on the other hand, maintain a constant output current regardless of changes in the load or input voltage. This helps to ensure that the LED maintains a consistent level of brightness over time and provides a high level of protection for the LED against over-current and over-voltage conditions. Constant current LED drivers are commonly used in applications where consistent lighting performance is required, such as in commercial lighting, architectural lighting, and retail lighting.
Both selectable current and constant current LED drivers are available in various form factors, including standalone units, plug-in modules, and integrated solutions. The choice between the two types of drivers will depend on the specific requirements of the application, including the desired level of control and the need for consistent lighting performance.
