LeaXield™ EMC Filters

TDK Corporation has reengineered and improved the EPCOS LeaXield active leakage current filter, a unique solution that minimizes earth leakage currents in converter-based drive systems.

LeaXield is available for load currents of up to 50 A at a rated frequency of 50 Hz/60 Hz and phase-to-phase voltages of up to 520 VAC. The active leakage current filter is connected between the RCD and the EMC input filter of the converter in industry-standard three-phase TN power grids and does not require an additional power supply. LeaXield can be utilized for earth leakage currents of up to 1 A and can effectively compensate leakage currents over a wide spectral range from 150 Hz to approximately 30 kHz.

Due to its compact design, the LeaXield is also well-suited for retrofitting existing installations. As no external power supply is required, installation outlay is minimal.
