[ 3 ] AC reactors (ACRs)
Use an ACR when the converter part of the inverter should supply very stable DC power, for example, in
DC link bus operation (shared PN operation). Generally, ACRs are used for correction of voltage
waveform and power factor or for power supply normalization, but not for suppressing harmonic
components in the power lines. For suppressing harmonic components, use a DCR.
An ACR should be also used when the power source is extremely unstable; for example, when the power
source involves an extremely large interphase voltage unbalance.

Note 1: Generated losses listed in the above table are approximate values that are calculated according to the following
conditions:
- The power source is 3-phase 230 V/460 V 50 Hz with 0% interphase voltage unbalance ratio.
- The power source capacity uses the larger of either 500 kVA or 10 times the rated capacity of the inverter.
- The motor is a 4-pole standard model at full load (100%).
Note 2: A box (
) in the above table replaces S or E depending on enclosure.
