AC reactor (AC choke)
This is used to improve the input power factor of the inverter power supply, reduce harmonicsor suppress external surges.Install this option when the power supply capacity is 500 kVA or more and the power supplycapacity is 10 times or more than that of the inverter's capacity, or when a distortiongeneratingsource such as a thyristor or a large-capacity inverter is connected to the samewiring leads.
Note: In case of TOSVERT VF-S15, VF-nC3 and VF-S11, the maximum capacity of transformer is 200kVA.

The DC reactor is more effective than the input reactor in improving the power factor. Werecommend joint use of the input reactor, that is effective in suppressing external surges,when facilities where the inverter is to be applied require high reliability.
Connection diagram
|
Please install an AC reactor in primary side of inverters.There is not polarity between 'U, V, W' and 'X, Y, X'. |
|
In case of using control power supplybackup unit (option: CPS002Z), please connect CPS002Z wiring to secondary side of an AC reactor. |
|
For VFAS1 400V class 355 to 500kW and VFPS1 400V class 500 to 630kW, be sure toconnect the AC reactor in parallel. |
