Harmonic drive compliance becomes more critical every day. At AID, we focus on a full range of solutions from passive filters to active front-end drive — all to ensure that you continue running reliably, efficiently and in compliance of IEEE519 and EN-6100-3-2. We manufacture every type of low-harmonics drive, using the latest technology available. Everything we do is tailored to your needs. In general, the most comprehensive solution for harmonics is an Active Front End VFD. This technology is electronically based, not magnetically based. It meets the IEEE519 under every scenario and all loading conditions, regardless of voltage imbalance or source impedance. It is so advanced, it can actually correct for low-voltage conditions from marginal systems and correct power factor within the electrical system, saving you money.
