GERMANTOWN, Wis., April 18, 2024 /PRNewswire/ — TCI announced the latest addition to their HGA Active filter line – the 30A and 50A HGA Active Filters. These smaller sized filters offer the same harmonic mitigation in a smaller enclosure.
The HarmonicGuard® Active (HGA) filter is an elite system-applied harmonic filter that minimizes harmonics to less than 5% total demand distortion (TDD) at the point of common coupling. The HGA monitors the load current and reacts to changes immediately. By injecting a counter-current, the active filter cancels out harmonics and synchronizes the current and voltage waveforms while improving power factor to near unity. One HGA filter can handle multiple non-linear, harmonic-generating loads.
The HGA meets the demanding requirements of IEEE-519 2022. Offering top of the line performance and mitigation, the HGA provides a lower cost and a smaller footprint than a comparable 18-pulse VFD or active front end drive.
Ashish Bendre, President of TCI commented,
“Motors with integrated drives are starting to dominate certain market segments – ECM fans in chillers, fan walls and air handlers are an example. The harmonic signature of these drives is quite different than that of a typical six pulse drive and traditional filters may not be effective. The advanced controls and power features in the new 30A and 50A filters enable these units to provide a clean power interface for ECMs. We believe that this gives our customers an effective solution that works seamlessly for a variety of ECM and standard drives.”
TCI’s full line of HGA filters are available in sizes ranging from 30 – 700A, with 208 – 600 V compatibility. They feature TDD reduction to less that 5% at full load, the ability to parallel units without any calibration, and offer communications through Modbus RTU over RS485, Modbus TCP/IP, EtherNet/IP, and BACNet/IP.
