In industrial automation, precision and uptime are everything. Electrical noise can disrupt sensors, PLCs, and servo drives—making EMI power line filters indispensable.
Q1: What causes EMI in factories?
Variable-frequency drives, welding equipment, and switching power supplies generate strong electromagnetic noise that travels through power lines.
Q2: How do filters help?
Installed on machine power inputs, EMI filters suppress interference, preventing malfunction of control circuits and ensuring smooth communication between devices.
Q3: What are the benefits for automation systems?
They enhance stability, reduce maintenance downtime, and prolong component life. Filters also ensure compliance with IEC and CE EMC standards for industrial machinery.
Q4: What about multi-phase equipment?
Three-phase EMI filters handle high-power loads, providing strong common-mode and differential-mode attenuation up to 100 A or more.
For factories moving toward smart automation, investing in reliable EMI power line filtering is key to achieving both efficiency and reliability.
