Passive Harmonic Filters

ECOsine™

A better way to Power Quality Schaffner ECOsineTM harmonic filters represent an economical solution to the challenge of load-applied harmonics mitigation in three-phase power systems. With a plug-and-play approach and more compact dimensions than comparable products, they can be quickly installed and easily commissioned. They increase the reliability and service life of electric installations, help utilize electric system capacity better , and are the key to meet Power Quality standards such as IEEE 519. Schaffner ECOsineTM harmonic filters provide:

• Efficient mitigation of harmonic currents.
• Compliance with IEEE 519 and other Power Quality standards.
• Increased equipment service life and system reliability in mission-critical applications
• More efficient utilization of electric system capacity (e.g. distribution transformers)
• Long-term savings in system operation and maintanance cost
• Support energy savings
• Fast and simple plug-and-play operation
• Very compact and light-weight filter concept
• Seamless integration with previously installed DC chokes or EMC/EMI filters

ECOsineTM filters calm your harmonic waves. Shaffner ECOsineTM filters 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. Typical applications, where the above-mentioned non-sinusoidal consumers of power can account for a significant portion of the load , include:

• Equipment with front-end six pulse rectifier
• Motor drives
• Factory automation equipment
• UPS and three-phase power supplies
• Water/wastewater treatment facilities
• Oil and gas exploration
• Heavy industry and machinery
• Self contained system (e.g. ships)
• Fan and pump applications
• Battery chargers
• HVAC installation
• Mission-critical processes
