ОПИСАНИЕ ПРОДУКТА
ALLEN BRADLEY 4983-PF120-30 - Industrial Harmonic Filter Module
This component is an industrial harmonic filter module designed for integration into power distribution systems to mitigate harmonic distortion. It functions by reducing total harmonic current distortion (THDi) generated by non-linear loads such as variable frequency drives (VFDs), rectifiers, and uninterruptible power supplies (UPS). The module enhances power quality, improves system efficiency, and ensures compliance with IEEE 519 standards in industrial environments.
