EMI/EMC Power Line Filters for industrial Electrical Systems

United Automation is a leading UK manufacturer of industrial power control solutions, and one of the key components in ensuring clean and reliable power is our range of Power Line Filters—also known as EMI / EMC filters. Designed to suppress electromagnetic interference (EMI) and ensure electromagnetic compatibility (EMC), these filters are essential in maintaining stable and compliant electrical systems.

What Are Power Line Filters?

Power line filters are passive electronic devices that reduce or eliminate electrical noise, particularly electromagnetic interference (EMI) and radio-frequency interference (RFI), from the mains power supply. These unwanted disturbances can affect the performance and reliability of sensitive equipment.

By placing EMI filters between the power source and your electronic devices, you can:

• Improve system reliability
• Reduce downtime
• Comply with EMC standards
• Avoid signal disruption in nearby equipment

United Automation’s filters are engineered for industrial robustness and provide cost-effective EMI suppression across a variety of voltage and current ratings.

Applications of EMI / EMC Filters

Power line filters are critical in many industrial and commercial applications where electromagnetic noise is a concern, including:

• Automation and control panels
• Industrial machinery and drives
• Medical equipment
• Telecom and data centres
• Consumer electronics manufacturing
• LED lighting systems
• Power supplies and inverters

They are especially vital in environments where high switching frequencies or sensitive data communications are present, preventing EMI from disrupting system operations.

Who Needs Power Line Filters?

Our EMI / EMC filters are designed for a wide audience of technical professionals and organisations, including:

• Electrical engineers and system integrators
• EMC Labs
• Industrial control panel builders
• OEMs (Original Equipment Manufacturers)
• Facilities managers maintaining EMC compliance
• Product designers seeking CE and FCC certification
• Automation and robotics manufacturers
• Medical device manufacturers

If your equipment or facility must meet electromagnetic compliance standards, integrating a power line filter is not optional—it’s essential.
