Power factor refers to the relationship between effective power and total power consumption, that is, the ratio of effective power divided by total power consumption. Basically, the power factor can measure the degree of power standby effective utilization. The higher the power factor value is, the higher the power utilization rate will be. POWERGOOD's upcoming 3-phase PFC has an efficiency of 97% and provides 3K-5K watts without cooling tools, and can be used in harsh environments.
