| Message: | LED drive power is the power supply is converted into a certain voltage current to drive the LED voltage converter,Website:http://www.loleds.com, normally: LED drive power supply input, including high voltage ac power frequency (mains), low voltage, high voltage direct current, low voltage high frequency ac dc (such as the output of electronic transformer). And the output of the LED driver power supply are mostly can change with LED positive pressure drop values and change the voltage of the constant current source. |
