4. Working Principle

1. Power Input: AC power enters the filter and activates the multi-stage LC filtering network.
2. Hierarchical Interception: Inductors and capacitors attenuate and bypass differential-mode line noise and common-mode ground noise separately.
3. Grid Noise Purification: Filters high-frequency harmonics and spike interference from the grid to output pure power for terminal loads.
4. Reverse Isolation: Blocks switching noise and harmonic feedback from frequency converters and switching power supplies to avoid grid pollution.
5. Shielding Stabilization: Metal shell shields external electromagnetic interference to ensure stable operation of precision devices.
6. Continuous Filtering: Real-time dynamic filtering maintains long-term power cleanliness and system anti-interference performance.
