Vertiv™ Liebert® AF4
Vertiv proudly introduces its first product line-up "Vertiv™ Liebert® AF4" an Active Harmonic Filter (AHF) to cater to the present industrial needs.
Specifications
Vertiv™ Liebert® AF4 identifies the downstream load current composition (such as active, reactive, harmonics, and unbalanced components) using an intelligent artificial neural network (ANN) based control technique and cancels the unwanted components at the load end through precise control of IGBTs.
Features
Vertiv™ Liebert® AF4 assures the plant current THD to stay below the limits specified by the IEEE 519-1992 with full dynamic compensation.
Vertiv™ Liebert® AF4 ensures unity power factor operation of the plant. Fully dynamic compensation adaptive to load changes.
Ability to cancel all odd harmonics up to 51st order. These harmonics are individually selectable/programmable with on limitation.
Vertiv™ Liebert® AF4 assures the plant current drawn from the EB to be balanced and sinusoidal.
Light in weight, compact in size, quiter in operation, and best in the performance.
Vertiv™ Liebert® AF4 in general, does not require the installation of input chokes with VFDs, as long as the load current THD is below 40%.
Vertiv™ Liebert® AF4 consists of an intelligent on the fly real-time internal switching loss minimization technique to enhance the internal energy
A 3P4W Vertiv™ Liebert® AF4 fully supports the load neutral current locally, and assures zero neutral current on the source/EB side.
