The ECOSine Active 30/50/100A is a harmonic filter that provides harmonic compensation in real-time. With a capacity of 100A, operating at 480VAC (+/- 10%), the 30/50/100A (3-wire) models are the smallest, most compact version which is easy to install in most industrial and commercial environments. They are ideal for manufacturing environments with nonlinear loads, such as variable frequency-motor drives, Uninterruptible Power Supplies (UPS), HVAC equipment, data centers and banking/heavy computing, and more. Open type or cabinet options are offered in NEMA 1, NEMA 3R and other protection ratings. Up to 5 units can be installed in parallel to attain optimal results.
