All-pole sine filter

All‑pole sine filters from the SF4 series combine all of the benefits of Future Winding technology. They allow unshielded motor cables to be used and optimize the drive’s EMC performance overall. Common mode currents are reduced with this while leakage currents are also minimized. The SF4 products from BLOCK improve the cooling effect and achieve lower proximity losses thanks to the latest winding and production technologies combined with the latest scientific findings. This ensures that their performance is optimized in particular compared with similar sine filters on the market.
