The FR-XC-(H)15K or lower does not have the harmonic suppression function.

Harmonic suppression (K5 = 0) achieved

The FR-XC series converter is classified as the self-excitation three-phase bridge circuit under the "Harmonic Suppression Guidelines for Specific Consumers" and achieves K5 = 0 (conversion factor for equivalent capacity) when its harmonic suppression function is enabled and in use with the dedicated box-type reactor FR-XCB.
(It is assumed that the converter generates no harmonics.)

The total harmonic distortion of the input current (THDi) is 5% or less^*1, which facilitates compliance with the overseas standards related to harmonic suppression.
*1When the input voltage is distorted, harmonic contents increase because power harmonics flow into the FR-XC series converter.
The waveform with high peaks, which is typical of the input current to the inverter section from the converter section in an inverter unit, is rounded to make a sine wave with a lower input current effective value.

Power supply capacity reduced by power factor improvement

With the reduced effective value of the input current to the inverter section, it is possible to install a power transformer, MCCB, cables, etc. with smaller capacity on the converter input side to reduce the equipment cost.

Wire and space saving

The slim converter requires less space, and the FR-XCB box-type reactor^*2 enables wiring reduction as it contains peripheral devices such as reactors.

*2Used for the FR-XC converter in harmonic suppression mode.

Space saving by increasing the current rating

When the 40°C rating of surrounding air temperature is selected within the temperature derating range, the current rating and the current to be applied can be increased. When the FR-XC series converter is intended for the use at the surrounding air temperatures less than 40°C, a model with a smaller capacity is applicable. With smaller converter, less space is required.

Installation space reduced by 40% or more

FR-XC-H75K: Width is reduced from 1000 mm to 600 mm.

FR-XC-H160K: Width is reduced from 1800 mm to 1000 mm.
