1Product Selection Notice
1、HFLIdeal for input to VFDs or other 6-pulse rectifiers, 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 connecting device must be grounded.
4、HFLAfter shutting off the power, wait for the intermediate circuit capacitors to discharge 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 the load power, HFL can achieve good filtering effects. Larger power HFLs can be used for smaller load powers, but the filtering effect will be reduced.
6HFL can power multiple VFDs, but the total load must not exceed HFL's rated power capacity.

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 Full Load Current THDI of the VFD is reduced below the typical value at the HFL rated load. In cases where these conditions are not met or only partially met, harmonic reduction can still be significant, but it will not reach the rated THDI 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. | |||
