Main functions
EMC and harmonic control
Suppress high-frequency interference and harmonics on the power supply side, meeting IEC 61000‑6‑4 standards, and reducing pollution to the power grid.
Integrated design
Built-in incoming line filter, electromagnetic contactor, surge voltage-sensitive resistor and harmonic filtering circuit, simplifying wiring and saving cabinet space.
Matched with 8720MC regenerative power supply
Designed specifically for **8720MC-RPS190BM/BS (190A regenerative power supply)**, using 8720MC-LR10-100B incoming line reactor.
Protection and immunity
Capable of suppressing overvoltage and surge, enhancing the stability of the variable frequency system in harsh power grids.

Typical Applications
Metallurgy: Rolling mills, conveyor belts, main drive (8720MC frequency conversion system with high power).
Mining / Cement: Ball mills, crushers, elevators (190A level regenerative power supply drive).
Alternative Note: The original factory has discontinued production. Please select a compatible filter or a new series power supply solution according to the engineering requirements for replacement.
