PF of Low Voltage Led Driver


The power factor (PF) is the ratio of useful work to apparent power. That is say, the higher the power factor, the more efficient the system operation.


Example of increasing the power factor meaning: The power of the device is 100 units, that is, 100 units of power are delivered to the device. However, since most of the electrical systems have inherent reactive losses, only 70 units of power can be used. Unfortunately, although only 70 units are used, low voltage led driver bureau has to pay 100 units, where the power factor is 0.7.


LED driver as a green energy-saving product should meet the requirements of the corresponding indicators.
