3AC filter reactorDFD accor. IEC/DIN EN61558-2-20 und UL1446

overviewtechnical data

Purpose and description

The use of a filter circuit reactor of the Schmidbauer DFD series will result in the filter circuit reactors that are created in compensation systems. Used in reactive current compensation systems and form with the capacitors of the reactive current compensation system a series resonant circuit and allow the necessary reactive power.

For frequently choosen chokes of 7%, the resonant frequency of the series resonant circuit formed by the filter circuit choke and the compensation capacitors is 189 Hz. With a throttling of 14% results in a resonance frequency of 134Hz.

The filter circuit choke also protects the capacitors of the compensation system.

The use of high-quality raw and insulating materials, in particular according to our UL insulation systems class B and F, as well as a careful processing “Made in Germany” guarantee a long service life. The DFD series is designed as an iron core choke to meet the increasing demands of inductive compensation or choked compensation stages. Iron core chokes by Schmidbauer with the Green Core principle with the aim of achieving very low total losses tailored to customer requirements.
