EMC filters and ground meshes are essential components for electromagnetic compatibility in industrial electrical installations. These devices, also known as RFI filters, EMI suppression filters, or mains filters, are designed to attenuate conducted electromagnetic interference generated by power electronics, variable frequency drives, switching power supplies, and other non-linear loads. Ground meshes, also referred to as equipotential bonding grids or grounding grids, provide a low-impedance path for high-frequency currents, ensuring proper shielding effectiveness and reducing common-mode noise. Key technical parameters include rated current (from 1A to several hundred amps), rated voltage (typically 250VAC to 690VAC), insertion loss (measured in dB across frequency ranges from 150 kHz to 30 MHz), and leakage current. Filter topologies include single-stage and multi-stage designs, with options for delta or star configurations. Ground meshes are characterized by mesh size, conductor cross-section, and material (typically tinned copper or stainless steel).
These components are deployed in a wide range of industrial sectors and environments. In manufacturing plants, they are installed in control cabinets, motor control centers, and distribution panels to protect sensitive PLCs, sensors, and communication networks from electrical noise. In renewable energy systems, such as solar inverters and wind turbine converters, EMC filters ensure compliance with grid codes and reduce harmonic distortion. Ground meshes are critical in data centers, telecommunications rooms, and medical facilities where electromagnetic interference can disrupt critical operations. They are also used in railway signaling, aerospace test facilities, and laboratory environments requiring stringent EMC standards.
Our catalog includes several subcategories and key article codes. For EMC filters, we offer single-phase filters (e.g., series FN2010, FN2030) and three-phase filters (e.g., series FN3258, FN3359) with various current ratings and connection types. Ground meshes are available in standard sizes like 50x50mm, 100x100mm, and custom dimensions, with article codes such as GM-50-1.5 (50mm mesh, 1.5mm wire) or GM-100-2.0. The coding typically follows a pattern: prefix for type (EMC or GM), followed by dimensions or current rating, and then optional suffix for special features like IP rating or mounting type.
Partnering with Electric Automation Network ensures fast, reliable access to these critical components. We offer express worldwide shipping, real-time pricing, and detailed technical documentation for each article. Our team of specialized engineers provides personalized support for selection, sizing, and compliance with international standards like IEC, EN, and UL. Whether you need a standard filter or a custom ground mesh solution, we deliver technical expertise and logistics efficiency to keep your projects on schedule.
All ratings we receive from the items we offer are real and verified. A small gesture, but a lot of value. That's why we thank you for that minute you invest in leaving us your opinion and qualification about the products, because it helps us to continue improving and to offer you a service of even higher quality.
