MAKING MODERN LIVING POSSIBLE VLT® Line Filter MCC 107 The VLT® Micro Drive Line Filter combines a harmonic filter and an EMC filter to improve the low frequency and high frequency performance of the line current to the VLT® Micro Drive. Increased drive lifetime Reducing the voltage ripple on the DC link will result in higher reliability and longer drive lifetime. Under similiar running conditions (temperature, load), the expected lifetime of the DC capacitors may be extended by 2-3 times. Improved power-factor The VLT® Line Filter will reduce the RMS value of line current. A smaller line current means higher true power-factor (PF). Typically, line current can be reduced by more than 40% and improve PF from 0.4 to 0.7 for single-phase drives and 0.47 to 0.9 for three-phase drives. Improved high frequency conduction EMC performance The VLT® Line Filter ensures compliance with EN55011 class A1 for up to 50m of motor cable, and class B up to 10m of motor cable. That means the VLT® Micro Drive + VLT® Line Filter, has an outstanding EMC performance in the micro- inverter class, even with relatively long motor cables. High immunity against grid disturbances The line filter will reduce the harmonic current drawn from the grid. The drive will comply with IEC61000-2-2 and IEC6100-2-4 without power derating, including 15% harmonic voltage distortion, 3% voltage imbalance and commutation notches, as described in IEC60146-1. With the line filter, the performance of the immunity to the surge and burst impact of the drive stated in IEC61800-3 will be greatly improved. Perfect match for: – Meeting harmonics recommen- Features Reduces the voltage ripple on the DC link Reduces the RMS value of line current Compliant with EN55011 class A1 up to 50m of motor cable, and class B up to 10m of motor cable The line filter will reduce the harmonic current drawn from the grid.
