As one of the largest EMI-RFI filter manufacturers in the world, Enerdoor offers solutions to customers needing an EMI-RFI filter in conjunction with single or multiple variable frequency drives (VFDs) and servo drives.

Thanks to IGBT technologies, machines and electronic devices are using VFDs inside their systems. The reason for this rapid proliferation is the versatility the IGBT gives the VFD. Many industries, including those listed below, are beginning to see the advantages of using this technology.

  • Machinery
  • Coolers
  • Uninterruptable power supply
  • X-ray inspection machines
  • Conveyers
  • Battery rechargers
  • Electric vehicles
  • Heavy construction equipment (excavators, mining machines, grinders)

VFDs and SCRs are commonly found inside industrial factories. However, this technology is proliferating into many other areas. For example, VFDs are found in the following locations:

  • Hospitals
  • Commercial malls
  • Commercial buildings
  • Theme parks
  • Airports
  • Stadiums

Enerdoor works with customers to minimize the electrical interference generated by VFDs, SCRs, servo drives, and other sources, regardless of the location. We analyze each problem and offer the best filtering solution to resolve the problem.

Enerdoor Parallel Filters are very useful in many situations. This design, unique to Enerdoor, attenuates noise in the low frequency range. The parallel nature of the filter makes it independent from the current in the system. Manufactured in a compact case with DIN rail mounting, the parallel filter eliminates any possible source of electrical noise generated by VFDs and SCRs.
