Product Description

Com-Power CDN-C50E

It is one of the series of Coupling/Decoupling Networks designed to comply for testing product for conducted immunity per IEC/EN 61000-4-6 and CISPR 16-1-2. The CDN-C50E is designed for testing products that uses 50 Ohm coaxial cables for data communication. It has 50 Ohm BNC connectors for both EUT and AE power connection. The CDN-C50E can handle up to 1 Amp of current. The RF disturbance signal coupling port is female BNC. It can handle up to 40V of RF Input Voltage. The bottom surface of the CDN is not painted for easy and effective grounding. This is a pre-packaged solution that includes an ACS series power amplifier and all accessories required for the test. Com-Power CDNs are individually calibrated. All Com-Power CDNs can be purchased separately or as part of the CIS series conducted immunity test system.

Compower CDN-T8SE

It is used during conducted emissions or immunity tests on devices with signal/telecom ports intended for connection to shielded (or screened) lines with up to four balanced pairs. The EUT and AE ports of the CDN-T8SE are equipped with shielded RJ45 receptacles. The RF input/output port is located on the top side of the network, and is fitted with a female BNC- type connector. The outer surface of the network’s metallic enclosure is powder coated for durability, and is mounted onto an untreated (conductive), stainless steel base plate. The base plate extends beyond the footprint of the network enclosure at the front and back, providing convenient access to effectively ground the network, which is essential. Any individual Com-Power CDN may be purchased separately, or as part of a CIS series conducted immunity test system. Test systems also include an ACS series power amplifier, as well as the required accessories.
