When Using A Constant Voltage Power Supply For LED Lamp Group What Kind Of Request?
Constant voltage power supply's output voltage must match the operating voltage of the LED lamp group, such as: constant voltage power supply with an output voltage of 12V,LED light group's operating voltage of each branch must also be 12V,LED number of modules at the maximum output current range increasing or decreasing. Due to the LED on-State voltage drop error, each branch of the pressure drop will be biased, each branch current is not the same, each branch should be concatenated dividing resistors or current-limiting measures.
