With the introduction of the new modular high power filters, Schaffner is further expanding its product offering of harmonics mitigation solutions. By utilizing the new filter modules, every high-power AC or DC motor drive can be easily upgraded to a low harmonic drive. The new modular filter concept specifically targets the requirements of integrators and their challenge of fitting a considerable amount of electrical equipment into tight motor control centers and electrical cabinets. The chokes module is designed for easy placement at the bottom of the cabinet, while the capacitor and RC-damper modules can be placed wherever cabinet space is available. The new filters don't need a dedicated expensive enclosure. The solution can be incorporated into the customers own cabinet, allowing the filter components to be wired along with the overall electrical wiring job and to be cooled by jointly utilizing the overall cooling concept. The modular high-power filters come in two versions: FN3410 filters for 380-500V, 50Hz grids, available with standard ratings from 200 to 400kW. And FN3412 filters for 380-480V, 60Hz grids, available for power ratings from 300 to 500HP. Filter modules are UL-recognized, CE-marked and RoHS compliant. They are particularly suitable for applications involving variable speed drives with DC-link chokes, where the total harmonic distortion (THD) of the load current must be reduced to ~5%. Other applications include high power battery chargers, UPS, three-phase power supplies and other equipment with balanced 6-pulse rectifier front-end.
