TE Connectivity / SchaffnerPassive Harmonic Filters
Ecosine Evo & Ecosine Max
Passive harmonic filters, Ecosine Evo (FN 3440 / FN 3441) and Ecosine Max (FN 3472 / FN 3481) · TE Connectivity / Schaffner
Passive harmonic filters that bring the distorted current drawn by 6-pulse rectifiers and motor drives back towards a sine wave — the direct route to the limits in IEEE 519. Ecosine Evo covers 1.1 to 250 kW at 400 V / 50 Hz with 5 % THDi at rated power (FN 3440, FN 3441); Ecosine Max is an open panel design for cabinet integration from 209 to 560 kW (FN 3472, FN 3481). Both are plug-and-play: nothing to commission, no switching losses and no parts that wear.

Applications
- Low Voltage Reactive Power Compensation SolutionsIn industrial and commercial facilities the reactive power balance can be upset both by inductive loads such as motors and transformers and by loads with a capacitive effect such as UPS systems, drives and long cable runs. This can disturb the reactive power balance, move the power factor away from the desired level, draw unnecessary current from the network, increase losses and incur reactive energy charges. Low voltage compensation systems hold the power factor at the desired level by providing compensation matched to the facility's inductive or capacitive reactive power demand. Where load changes are rapid, thyristor-switched systems are used to respond quickly to reactive power variation. In facilities where harmonics are present, compensation systems with harmonic filter reactors are applied to keep the capacitors from entering resonance with the network. A correctly engineered compensation system helps to avoid reactive energy charges, to use transformer and cable capacity more effectively, to reduce electrical losses and to improve system performance.
- Harmonic Filter SolutionsNonlinear loads such as frequency converters, rectifiers, UPS systems, power electronics equipment and arc furnaces can cause current and voltage harmonics on the network. High harmonic levels lead to overheating in transformers, cables and capacitors, to increased energy losses, to a risk of resonance and to unexpected failures in sensitive equipment. Harmonics are reduced with active or passive harmonic filter solutions selected according to the facility's load structure and harmonic spectrum. Passive harmonic filters are effective at reducing specific harmonic components, while active harmonic filters compensate harmonics in real time under variable load conditions, providing dynamic filtering. At EPKOM we determine the filter type and capacity that suits the facility from power quality measurements and harmonic analysis, and engineer our solutions taking IEEE 519 and the relevant IEC/EN standards into account. This reduces harmonic levels, protects equipment and allows the electrical system to run more safely and efficiently.
