If you are replacing the driver, be sure to match the input and output requirements of the old driver as much as possible

Constant current led drive

The constant current led driver is designed as a led lamp, which requires a fixed output current and output voltage. This type of driver will have a specified output current marked as amperes, and the voltage range will vary according to the LED power rating. Using a higher ampere rate will make the light-emitting diode brighter; however, it will eventually exceed the driving led, thereby reducing the life span and premature failure. Because constant current drives maintain consistent brightness, they are commonly used for signs, backlights, and commercial LED displays.

Constant voltage led drive

On the other hand, to design a constant voltage Triac Dimmable LED Driver for LEDs, it requires a fixed output voltage whose output voltage is the maximum output current. Led lights are driven by a constant voltage, and the output voltage is required to be consistent, usually 12V DC or 24V DC. This type of 120w led driver receives a standard voltage, about 120 to 277 volts in the form of AC voltage, and drives it to convert it to a low DC voltage.
