This power supply uses an active PFC circuit
This power supply has excellent performance and has an active PFC circuit to satisfy buyers with high performance requirements. The following is an introduction to PFC from the Internet for reference
PFC (Power Factor Correction)
The full English name of PFC is “Power Factor Correction”, which means “Power Factor Correction”. Power factor refers to the relationship between effective power and total power consumption (apparent power), that is, effective power divided by The ratio of total power consumption (apparent power). Basically, the power factor can measure the extent to which electricity is effectively utilized. The larger the power factor value, the higher the power utilization rate.
Power factor is a parameter used to measure the power efficiency of electrical equipment, and low power factor represents low power efficiency. The technology to improve the power factor of electrical equipment is called power factor correction.
There are currently two types of PFC, one is passive PFC (also known as passive PFC) and active PFC (also known as active PFC)
The filter capacitor of the power supply itself is sufficient for daily use, or you can add a filter capacitor board to increase the filter capacitance.
