Suited for use with non-linear loads, ECOsine® 60 Hz Passive Harmonic Filters increases reliability of supplied power and extends service life of downstream components by removing harmful harmonics of pre-determined order. Plug-and-play design facilitates installation and commissioning and suits new installations and retrofits. Installed at typical 3-phase voltage of 480 Vac (±10%), at 60 Hz (±1 Hz), filters operate at 98% efficiency and reduce harmonics to 7%–10% THDi.
