For CC applications, an incorrect output current can cause unstable operation or LED damage. For CV applications, an incorrect output voltage can cause overheating, unstable operation, or LED damage. Always match the power supply's output specifications to the LED fixture requirements.
Both CC and CV LED drivers can support different dimming and control methods depending on the model, including 0-10V, DALI-2, D4I, TRIAC, DMX512,Matter, Thread Wireless control.
It allows users to select different output-current levels using a DIP switch or NFC, making one CC LED driver suitable for multiple LED load requirements.
CC LED driver typically provide a specific output-current range, such as 100mA–2100mA, while CV LED driver provide fixed output voltages such as 12V, 24V, 36V, or 48V.
Check the LED fixture specifications. For CC applications, match the required output current and LED forward voltage. For CV applications, match the required output voltage and total load wattage.
CC LED driver are commonly used for LED downlights, COB LEDs, LED modules, spotlights, panel lights, ceiling lights, floodlights, street lights, and high bay lights. CV LED driver are commonly used for LED strips, LED panels, cabinet lighting, linear lighting, and signage.
CC LED driver maintain a fixed output current, with some models offering adjustable current settings through a DIP switch or NFC. CV LED driver maintain a fixed output voltage, such as 12V, 24V, 36V, or 48V.
