PFC is the acronym for power factor correction or power factor controller. It minimizes the amount of reactive power produced by computers.Why should a PFC power supply be connected to an uninterruptible power supply?It also reduces the cost of electricity by minimizing the amount of reactive power produced by computers and other devices. The PFC power supply should be connected to an uninterruptible power supply (UPS) to ensure the devices have suitable power in case the main power source goes out.
Does a power supply have a PFC?A power supply with PFC can supply higher output load currents than those without PFC. PFC significantly reduces the AC current harmonics, leaving mainly the fundamental current frequency that is in-phase with the voltage waveform. International regulations dictate the substantial reduction of harmonic currents.
What is PFC & how does it work?PFC is the acronym for power factor correction or power factor controller. It minimizes the amount of reactive power produced by computers.
