Options for the FR-A842 Serving as a High Power Factor Converter
Características
FR-A842 inverter serving as a high power factor converter with the following options
Only 5% or less of the total harmonic
distortion of the input current (THDi)*
Such a low rate of THDi facilitates compliance with the overseas standards related to harmonic suppression.
*When the input voltage is distorted, harmonic contents increase because power harmonics flow into the converter.
Harmonic suppression (K5 = 0) achieved
The FR-A842 converter (converted from the FR-A842 inverter by using the plug-in option FR-A8AVP) is classified as a self-excitation three-phase bridge circuit under the "Harmonic Suppression Guidelines for Specific Consumers" and achieves K5 = 0 (conversion factor for equivalent capacity).

Turn spare inverters into converters
Inverters can be used as high power factor converters. They can be switched to a converter and back to an inverter again to match process requirements.
