What is Power Supply

- May 21, 2020-

The LED power supplier is a voltage converter that converts the power supply to a specific voltage and current to drive the LED to emit light. Generally, the input of the LED driver power supply includes high-voltage power frequency AC (that is, commercial power), low-voltage DC, high-voltage DC, low-voltage high Frequency AC (such as the output of electronic transformer), etc. The output of the LED drive power supply is mostly a constant current source that can change the voltage as the forward voltage drop of the LED changes.
