Converter ratings and specifications

Options for the FR-A842 Serving as a High Power Factor Converter

*1DC output capacity when the input voltage is 400 VAC. Multiple ratings are not supported.

*2Change the stepdown transformer tap according to the input voltage.

*3The output voltage is approx. 594 VDC at an input voltage of 400 VAC, approx. 653 VDC at 440 VAC, and approx. 742 VDC at 500 VAC.

*4The percentage of the overload current rating is the ratio of the overload current to the converter's rated input current. For repeated duty, allow time for the temperatures of the converter and the inverter to return to or below the temperatures under 100% load.

*5FR-DU08: IP40 (except for the PU connector)

*6The permissible voltage imbalance ratio is 3% or less. (Imbalance ratio = (highest voltage between lines - average voltage between three lines) / average voltage between three lines × 100)

*7The rated voltage when connecting a motor to the FR-A840-02160(75K) and FR-F840-02160(90K) and above. If connecting to inverters other than those mentioned above, the rated voltage is 380 to 480 V.
