CDN 405AF4 Coupled decoupled networks used to evaluate the lightning-surge resistance of low-speed unshielded asymmetric communication lines. It can be used to test 100KBit/s Ethernet, and the strong decoupling capability can protect the auxiliary device (AE) from surges, ensuring repeatability of the test. The maximum surge voltage is 6KV. This CDN will meet the IEC/EN 61000-4-5:2017 standard upgrade. It is designed in accordance with IEC/EN 61000-4-5 FIG. 9 Unshielded asymmetric low-speed data line standards. Decoupling performance and transmission rate are stable, small size and easy to carry and use.
Features：
> Can be used to test 100K Bit/s rate;
> 1/2/3/4 Wire Unshielded wire to wire/wire to ground;
> Coupling waveform 1.2/50 μs, 8/20 μs;
> Maximum working current 2A;
> The interface specification is 4mm banana head;
> Compatible with foreign generator output ports for communication testing;
> Replace current limiting resistors, couplers and decoupling devices according to test requirements

Note: When purchasing a CDN network, you must purchase a coupler and decoupling device from the optional components to use the CDN network. In addition, the residual pressure is related to the type of decoupling device, and the waveform and amplitude of the residual pressure of different decoupling devices are different.
