Active harmonic filters are filter systems used to filter high-frequency disturbances. The type-tested SLV series is designed for expansion and capacity increase with its modular panel structure.
Control Type: High switching frequency IGBT Module
Principle of Operation: Separate filtering on each phase and neutral line
Operation Type: Automatic / Selected harmonics
Connection Type: Pull-out design with plug-in bushing for fast serviceability
