The FFR-DT-500A-SS1 du/dt filter optimizes the output of 400 V inverters in high‑current applications up to 250 kW. By limiting dv/dt and attenuating reflected wave phenomena on long motor cables, it protects motor insulation, lowers stress on windings and bearings, and enhances reliability across industrial drives, pumps, HVAC, and conveyor systems.

Engineered for modern PWM drives, this open‑frame IP00 filter handles 500 A continuous current and supports switching frequencies from 2 to 16 kHz without compromising drive dynamics. Its low‑loss design (340 W at nominal) helps minimize panel heat, while the compact footprint streamlines cabinet layouts and supports adherence to common motor‑drive installation guidelines.

Whether upgrading existing lines or specifying a new VFD panel, this du/dt filter delivers predictable performance, easier motor selection, and reduced downtime, and it is backed by a 1-year warranty for added assurance in critical operations.
