Choosing constant current dc led driver or constant voltage dc led driver may the first things you need to take into consideration for your lighting projects. Here we would like to clear up the confusion of Constant Voltage and Constant Current LED Driver Power Supply.
If you’re having an LED lighting fixtures or replacing a constant current led driver module, it’s important to confirm that the output current and voltage of the led driver power supply is compatible with the LEDs’ current and voltage. If your LED lighting fixtures requires a constant-voltage power supply or constant-current driver, check the LED lighting fixtures’s specifications for its operating requirements, and make sure that it is compatible with the specifications of the power supply or driver.
Also be sure that the power supply or driver’s input voltage matches that of the location it will be installed in. If you have an LED product with 12-volt DC operation that you wish to use in a 120-volt AC home wiring system, you’ll need a power supply that includes 120 volts in its input range and has 12-volt DC output. A 24 volt DC power supply would not be appropriate because its output voltage isn’t compatible with the voltage of the product.
When choosing a constant current electronic led power supply for an LED project, ensure that the current and voltage requirements of the LEDs are met. If LEDs are in a parallel configuration, add all current values while keeping the voltage range steady. If LEDs are used in a series, add all voltage values, but keep current the same as an individual LED.
