CN 405AF4

The CN 405AF4 complies with IEC/EN 61000-4-5 and TB/T 3498. It is a professional CN developed for lightning surge immunity tests on railway power supply ports. It supports line-to-ground and line-to-line tests, with a max. pulse voltage of 10 kV. Suitable for line-to-ground and line-to-line tests on balanced communication transmission lines. It also supports line-to-ground and line-to-line tests for unbalanced communication transmission lines. Compact, portable and easy to operate.
