What's PFC? Which Power Supplies with PFC?

PFC( Power Factor Correction) is to increase the ratio of apparent power to real power. Power factor refers to the relationship between real power and apparent power, the calculation formulas are as follows: Apparent power = Input Voltage x Input Current(VA), Real Power = Input Voltage x Input Current x Power Factor(W). When the power factor is larger, it means that the power utilization rate is higher.

The power factor is around 0.5~0.7 in non PFC models. In models with PFC circuit, the power factor can reach above 0.92. Here is two types Power Supplies with PFC function:

1. ac dc adapter (120W to 200W series)

• PC plastic housing
• 100-240V Universal AC input
• Level VI energy efficiency
