Schaffner ECOsine filter cabinets (Filters for thyristor (SCR) ) can be applied to virtually any kind of power electronics with front-end six-pulse rectifiers, where harmonic current distortion needs to be reduced to defined limits. The compact filter cabinets can be easily commissioned and quickly installed into extisting designs without requiring an in-depth system analysis or highly trained specialists. Typical applications include higher power AC and DC motor drives with either six diode used e.g. in HVAC, water/wastewater, oil & gas, or mission critical factory automation equipment. In addition, ECOsine® filters can help to reduce thermal and electrical overload caused by harmonic currents in installations involving UPS, high power rectifiers and other nonlinear three-phase power supplies. several specifications of these filters are described as follow: -ECOsine high power passive harmonic filter performance is optimized for rectifiers/motor drives with a dc-link choke. In such applications, a THID of roughly 5% can be expected. The use of a dc-link choke is highly recommended. In a system without Ldc, the filter module has to be derated to max. 70% of its nominal power rating. -At full load, ECOsine filters yield unity power factor. At lower load levels, the capacitive current into the power capacitors of the trap circuit cause a leading displacement power factor. This is the case with all types of passive filters with large capacitors. However, compared to traditional filters the useful range of Schaffner ECOsine is much extended (cos phi >0.9 from 35 to 100% of rated load). -ECOsine harmonic filters have a very low impact on the dc-link voltage of the motor drive.
