Unsymmetrical Coupled Decoupling Network DATA-CDN-4B – IEC 61000-4-5 Surge Coupling Device

Unsymmetrical Coupled Decoupling Network | DATA-CDN-4B Surge Tester

The Unsymmetrical Coupled Decoupling Network (Model: DATA-CDN-4B) is a critical component for simulating lightning strikes and industrial switching transients on communication lines. As a specialized Surge Immunity Test Equipment, it enables the injection of high-voltage pulses onto high-speed data paths. Designed with a high-performance 10/700μs Decoupling Network, this apparatus supports pulse outputs from waveform generators and ensures that the Equipment Under Test (EUT) meets the rigorous transient requirements of global telecom standards.

KingPo Factory Advantages

KingPo (Dongguan) is a premier manufacturer of Electrical Safety Laboratory Testing Equipment. Our DATA-CDN-4B Surge Tester is built on over 20 years of R&D, combining high-speed IT technology with robust power electronics.

Professional Construction & Technical Precision

Every KingPo Unsymmetrical Coupled Decoupling Network is engineered for precision:

• Waveform Precision: Optimized for the 10/7o0μs Decoupling Network requirement,it allows for a 6 kV maximum test voltage while maintaining a 0.5 μF coupling capacitance
  for maximum energy transfer.
• Data Path Stability: The DATA-CDN-4B supports Gigabit (1oooM) network
  communications, making it the preferred Surge Immunity Test Equipment for modern ITinfrastructure testing.
• Resistance Matching: The network features a flexible plug-and-play resistance system（25,40,100,160,200,320 2), enabling technicians to calibrate the DATA-CDN-4B Surge Tester to specific circuit impedances.
• Safety & Shielding: Housed in a durable 440 x 350 x 150 mm enclosure, the network utilizes professional-grade decoupling inductors(20mH) to isolate high-voltage transients from the monitoring AE (Auxiliary Equipment).

Primary Use Cases & Business Value

• Network Infrastructure: Validating the surge protection of Gigabit switches and routers.
• Telecom Compliance: Using the 10/7o0μs Decoupling Network to meet international
  carrier safety standards.
• R&D Optimization: Identifying the breakdown limits of communication ports during the
  development of Surge Immunity Test Equipment.

Compliance & Regulatory Assurance

The DATA-CDN-4B is fully compliant with IEC 61000-4-5 and CISPR 16-1-2. Our engineering follows the protective recommendations for telecommunication lines issued by the ITU (International Telecommunication Union). Furthermore, data provided by the CPSC (U.S. Consumer Product Safety Commission) underscores the critical importance of surge protection in preventing electronic component failure.
