Product Overview

The LQLVF 225kVA/2*592.1A Power Noise Filter provides robust electromagnetic interference (EMI) suppression for industrial power systems operating at 0.38kV. Featuring dual 592.1A circuits and enhanced 10kV insulation, this filter delivers superior noise attenuation in high-current environments while ensuring operational safety and compliance.

Technical Specifications

Attenuation Performance

• 40kHz-100kHz Range: >40dB noise suppression

• 100kHz-1MHz Range: >60dB noise suppression

This advanced attenuation profile effectively eliminates harmonics and switching noise from high-power industrial equipment including motor drives, UPS systems, and power converters.
