VLT® Low Harmonic Drives | Dew Point

VLT® Low Harmonic Drives

VLT® Low Harmonic Drives

VLT® Low Harmonic Drives

The perfect solution for

  • Meeting the toughest harmonics recommendations and standards
  • Generator-powered installations
  • Installations with generator backup
  • Soft power grids
  • Installation of drives in grids with limited excess power capacity

Benefits
Low operating costs
saves energy
improved power factor
reduced load on supply network
lower transformer, switch- gear and cable losses
less control room cooling
less fan power consumption

Maximum uptime
maintenance free – problem-free operation in harsh environments

Save initial and operating costs – meeting toughest harmonics recommendations/ standards – optimized transformer/ generator grid capacity – more drives on same transformer – energy optimization

Low investment – low initial investment with maximum flexibility and possibility of future upgrades – reduced cost for wiring and external I/O controller – integrated EMC RFI-filters

Save commissioning and operation cost – userfriendly and easy to commission and operate – full overview and timely tracking of grid conditions
