1Product Selection Guidelines
1、HFLIdeal for input to VFD or other 6-pulse rectifier power supplies, nearly eliminating harmonic distortion.
2HFL achieves superior THDI performance, enhancing energy efficiency, ensuring your system fully complies with harmonic standards (IEEE-519, EN61000-3-2, etc.).
3、HFLAll electrical installations and maintenanceThe work should be performed by a qualified electrical engineer.HFLThe and connection device must be grounded.
4、HFLAfter power is cut off, wait for the intermediate circuit capacitors to discharge naturally for 3 minutes.Before performing operations at different levels, please use a multimeter to confirm that the HFL input/output terminals have been fully discharged.
5When used with load power matching, HFL can achieve good filtering effects. Larger power HFLs can be used for smaller loads, but the filtering effect will be reduced.
6HFL can power multiple VFDs, but the total load must not exceed the rated power of HFL.

Note (Remark): When the Total Harmonic Voltage Distortion (THVD) is below 2% (line voltage balance less than 1%) and the Short Circuit Power to Installed Load Ratio (RSCE) is greater than 66, the Total Harmonic Distortion Current (THDI) at full load of the VFD will be reduced below the typical value at the HFL rated load. In cases where these conditions are not met or only partially met, although harmonic distortion can still be significantly reduced, the THDI will not reach the rated value. When the THVD of the supply voltage is less than 2%(line voltage balance is less than 1%) and the short-circuit power to installed load ratio (RSCE) is >66, the THDI of the supply current at full VFD is reduced to HFL Below the typical value at the rated load, in the case that these conditions are not met or only partially met, although the harmonics can still be significantly reduced, it will not reach the rating of THDI. | |||
