Why Industrial Lasers Need Filtering
Industrial laser systems generate high-frequency electrical noise from power supplies, switching components, RF exciters, pulse generation circuits, and motor-driven subsystems. Without proper EMI/RFI filtering, this noise can interfere with sensitive control electronics, compromise precision operation, and create challenges in meeting EMC compliance requirements.
Available in multiple current ratings (50-600 amps), mounting styles, and configuration options, NexTek filters support integration into compact industrial designs while helping engineers improve system immunity, reduce interference between subsystems, and achieve reliable EMC performance. High-frequency attenuation extending beyond 1GHz helps support both emissions control and susceptibility protection in electrically noisy industrial environments.
