Four Conductor CDN for Power Line

Built for IEC/EN 61000-4-6 conducted immunity testing on power inputs from 150 kHz to 230 MHz, allowing controlled RF disturbance injection while the equipment remains powered and operating.
4-line design rated up to 25 A per line, commonly applied to single-phase AC mains with L, N, and PE plus an additional conductor (or multi-wire power arrangements where the EUT wiring includes multiple current-carrying conductors and protective earth).
Used when a product’s power entry must be tested as installed, with line, neutral, and protective earth present—for example, control cabinets, industrial power distribution modules, and equipment that includes auxiliary power conductors in the same feed.
Practical for immunity evaluation of industrial automation panels, PLC cabinets, machine control boxes, rack-mounted power systems, and embedded industrial equipment that must keep running while RF is coupled onto the power wiring.
Supports testing where the EUT must remain functional during RF injection—examples include maintaining controller operation, relay states, display/indicator stability, and communication uptime while the power conductors are stressed with common-mode RF.
Helps reproduce real-world susceptibility conditions caused by grounding and neutral behavior, such as unexpected resets, false triggers, sensor drift, communication dropouts, or nuisance faults that occur when RF couples onto the power feed and returns through PE/neutral paths.
Useful for verifying immunity under representative operating loads (light, nominal, or near-rated up to 25 A per line), so failures are caught before field deployment in electrically noisy environments.
Common choice for pre-compliance troubleshooting and final compliance runs, especially when engineers need a repeatable way to inject RF disturbances on the power entry without rewiring or simplifying the installation.
