Schaffner introduces the Ecosine filters
A Schaffner product story
Edited by the Electronicstalk editorial team Nov 18, 2008
Schaffner's Ecosine load-applied passive harmonic filters are suitable for three-phase power electronics with six-pulse rectifier front ends, such as AC and DC motor drives.
Rectifier peak and RMS input current are reduced and a pure sine wave is drawn from the grid.
For new installations, the use of ECOsine filters allows electric conductors, fuses, and breakers to be downsized, or enables a greater number of drives to be powered by a given size of distribution transformer.
Using Ecosine filters in new installations allows electric conductors, fuses and breakers to be downsized, or enables more drives to be powered by a distribution transformer.
They can be selected by actual input power demand of an individual load or a group of loads.
Their small size allows them to be installed inside the electrical cabinet next to the drive.
A plug-and-play concept allows quick installation, wiring and commissioning, without the need for specialists or system analysis.
A standard safety feature continuously monitors filter temperature, controls the internal fans and provides an NC/C contact for seamless integration into a machine or system control unit.
Ecosine FN 3410 filters are designed for 380-500V, 50Hz grids and are available for power ratings from 4 to 160kW.
FN 3412 filters are suitable for 440-480V, 60Hz grids with standard ratings ranging from 5 to 250HP.
Ecosine filters reduce total harmonic current distortion (THID) to < five per cent, which means they comply with IEEE 519 and other international power quality standards.
All filters are UL-approved, CE-marked and RoHS-compliant.
