Bảng điều chỉnh nguồn tự động (APFC)

Most commercial and industrial installations in country have large electrical loads which are severely inductive in nature, such as motors, large machines, air conditioners, drivers etc. Which results in severely lagging power factor. This means the loss of and loss of energy and heavy penalties by electricity boards. In the case of fixed loads this can be taken care by manual switching of capacitors. However, if you quickly various and scattered loads it becomes difficult to maintain high power factor by manually to switch on/off capacitors in proportion to variation of load within the installation. This drawback is overcome by using an APFC panel (automatic power factor correction) which not only maintains high power factor but also eliminates the need for constant manual intervention. Advantages "With faster economic payback. "The ability to maintain a constant high power factor. "Eliminates low power factor penalties levied by EB. "Reduces kVA demand charges. "Improves system efficiency by reducing losses. "To prevent a leading power factor of the installations in low-load conditions.
