What are CV, CC, and CV+CC which are often mentioned in LED power supply specification?

CV, CC, and CV+CC are modes of operation for LED power supplies. Here's a brief description of each:

1. CV (Constant Voltage) mode: In this mode, the power supply maintains a constant voltage output regardless of changes in the load current. This mode is commonly used for LED lighting systems that require a fixed voltage to operate, such as those with a constant voltage driver.

2. CC (Constant Current) mode: In this mode, the power supply maintains a constant current output regardless of changes in the load voltage. This mode is commonly used for LED lighting systems that require a fixed current to operate, such as those with a constant current driver.

3. CV+CC (Constant Voltage + Constant Current) Hybrid mode: In this mode, the power supply can operate in both constant voltage and constant current modes, depending on the load requirements. This mode is commonly used for LED lighting systems that require both fixed voltage and current to operate.

LED power supplies often come with multiple output modes, which allows them to be used with a wide range of LED lighting systems. By selecting the appropriate output mode, the power supply can provide the necessary power to the LED lighting system while maintaining proper voltage and current levels to prevent damage or failure of the LED components.
