Product Overview

The LQLVF 225kVA/2*562.5A Power Noise Filter delivers critical electromagnetic interference (EMI) suppression for industrial power systems. Engineered for integration into sub-stage switchgear cabinets, this dual-circuit filter protects sensitive equipment from high-frequency noise while maintaining operational stability in 0.4kV electrical networks.

Core Technical Specifications

Attenuation Performance

• 20kHz-100kHz Range: >40dB noise suppression

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

This exceptional attenuation profile eliminates harmonic distortions and switching transients from VFDs, inverters, and power converters.

Installation & Integration

Designed for direct installation in sub-stage switchgear cabinets with compact dimensions. The ONAN cooling system ensures zero-maintenance operation in ambient temperatures up to 40°C.

Key Integration Benefits:

• Prevents control system malfunctions from EMI

• Reduces bearing currents in motors

• Complies with IEC 61800-3 EMC standards

• Extends equipment lifespan by eliminating voltage spikes

Industrial Applications

• Manufacturing Plants: CNC machinery and robotic control systems

• Renewable Energy: Solar/wind farm power conversion units

• Data Centers: Critical server power supply protection

• Industrial Automation: PLC and drive system EMI suppression

Quality Assurance

All LQLVF filters undergo rigorous testing per IEC 60939 standards. The >70 Q-factor filtering reactor ensures minimal signal loss while maintaining peak attenuation efficiency across the operating temperature range.
