CDN for One Balanced Unscreened Pair

Designed for conducted immunity testing in full compliance with IEC/EN 61000-4-6 and CISPR 16-1-2, specifically for coupling RF disturbances onto one balanced unscreened pair used in communication and control interfaces.
Operates over a frequency range of 150 kHz to 230 MHz, covering the complete conducted immunity test band required by IEC/EN 61000-4-6.
Supports one balanced unscreened conductor pair using RJ11 connectors, making it suitable for two-wire telecom, control, and signal cables commonly found in industrial and commercial products.
Provides standardized 150 Ω common-mode impedance across the specified frequency range, meeting the impedance requirements defined by IEC/EN 61000-4-6 and CISPR 16-1-2.
Handles up to 40 V RF input and 2 A continuous current, allowing safe injection of specified disturbance levels during conducted immunity testing.
Features RJ11 connections for both EUT and auxiliary equipment and a 50 Ω BNC RF input, enabling straightforward integration into standard conducted immunity test configurations.
Individually calibrated with a defined voltage division factor, ensuring repeatable, consistent, and traceable test results when establishing calibrated drive levels.
Used to inject RF common-mode disturbances onto a single balanced unscreened pair while maintaining uninterrupted signal paths between auxiliary equipment (such as telecom simulators or communication analyzers) and the EUT (for example, industrial controllers, meters, or communication devices using two-wire interfaces).
Enables verification of conducted immunity performance for products using two-wire interfaces, including industrial controllers, meters, sensors, and communication devices with balanced lines.
Helps engineers perform pre-compliance and compliance testing to identify susceptibility issues on communication ports early, reducing redesign risks before certification testing.
Commonly used in EMC laboratories and in-house test facilities to validate conducted immunity performance of products prior to market release.
Supports complete conducted immunity test systems when used with Com-Power ADA-T2 shorting adapters, ADA-515-2 150 Ω to 50 Ω adapter sets, TEP-050 50 Ω terminator, and Com-Power ACS series power amplifiers.
