CHARGER
The UPS includes a 3-phase charger with PFC
2
PFC is a feature included that reduces the amount of generated reactive power. Reactive
power operates at right angles to true power and energizes the magnetic field. Reactive
power has no real value for an electronic device, but electric companies charge for both true
and reactive power resulting in unnecessary charges.
In power factor correction, the power factor (represented as "k") is the ratio of true power
(kwatts) divided by reactive power (kvar). The power factor value is between 0.0 and 1.00. If
the power factor is above 0.8, the device is using power efficiently. A standard power supply
has a power factor of 0.70-0.75, and a power supply with PFC has a power factor of 0.95-
0.99.
