TCI HSD0450AW11100 - HarmonicShield™ (HSD) with PQconnect, a cutting-edge passive harmonic filter designed to mitigate the adverse effects of harmonics produced by non-linear loads, particularly variable frequency drives (VFDs). Compliant with IEEE 519-2014 standards, this innovative filter limits current harmonic distortion to less than 5% across a wide load range, ensuring optimal performance even under harsh conditions. With features like intelligent control, maintenance-free design, and convection cooling, the HSD offers cost-effective and reliable harmonic mitigation solutions for a range of applications, from oil and gas pumps to HVAC systems. Available in a 3 HP to 1000 HP range and compatible with both 480 VAC and 600 VAC systems, the HSD with PQconnect is proudly made in the USA, providing industry-leading performance and peace of mind for critical infrastructure.
