Description

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.
