It is utilized in combination with a hold-up capacitor, a set of extremely efficient DC-DC converters, and an appropriateAC line filter. Backed by these components, the power factor correction modulestarts to draw a nearly ideal sinusoidal currentwith avalue‘PF>0.99’ from a single-phase AC input.
You can use the parallel circuit for up to three power factor correction modules to attain higher power. Such modules are supplied entirelyenclosed and encased to deliver protection against harsh conditions that are common in most industrial and transportation settings.
When Are Power Factor Correction Modules Used?
Power factor correction modules improve the power quality and accessibility by optimizing power consumptionand compensating for voltage drops due totransitory supply cuts, thus averts any negative impact on the process functioning and mechanisms.
Power factor correction (PFC) boosts the load’s power factor and improves the efficiency of the electrical distribution system. Linear loads with a low point power factor can be altered with a network of passivecapacitors and inductors. Non-linear loads require an active or passive power factor correction to counteract the distortion and increase the power factor.
Power factor correction can be started at a central substation and then spread out over a distribution system. Alternatively, it can also bebuilt into the power-consuming equipment.
Power factor correction modules arethoroughly tested solutions that are ideal for panel builders. It is a pre-wired in a sub-assembledlayoutto inserts it into the power factor correction cubicles that either functions as a standalone or is placed inside a Main Low Voltage Switchboard (MLVS). Similarly, power factor correction is available with or without an incorporated busbar for the various electrical distribution network types.
