Industrial automation cabinets are dense with sensors, drives, HMIs, and control logic. EMI can travel through power rails and compromise sensitive electronics, driving reliability concerns in manufacturing environments.
EMI originating from motor starts, braking choppers, and switching supplies can cause sensor drift, misreads, and occasional PLC resets.
Harsh environments, including temperature swings and electrical noise, amplify EMI challenges.
Install single-phase filters at the main input or near particularly sensitive subsystems to decouple the cabinet from external noise sources.
Filters mitigate conducted EMI without requiring changes to the primary control architecture.
Even simple power filtering upgrades in industrial control panels can yield outsized returns in reliability, uptime, and process consistency.
