The CDN-M125E is designed for testing products that uses a single conductor power cable. It has one 4 mm shrouded banana socket for both EUT and AE power connections. The CDN-M125E can handle up to 25 Amps AC and 17 Amps DC 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.
All Com-Power CDNs are individually calibrated. The Com-Power CDN-M125E fully complies with the requirement contained in the IEC 61000-4-6 and CISPR 16-1-2. All Com-Power CDNs can be purchased separately or as part of the CIS series conducted immunity test system. This is a pre-packaged solution that includes an ACS series power amplifier and all accessories required for the test.
During conducted Immunity testing, CDNs are utilized to provide a means of coupling RF common mode signals to each line. In addition, CDNs provide the required common mode impedance to the EUT, isolation to the auxiliary equipment via common mode decoupling of the disturbance signals and provide uninterrupted communication between the EUT and auxiliary equipment.
Before you begin testing with the CDN-M125E you will need to establish calibrated drive levels corresponding to your desired test levels. During drive level calibration, the RF signal level being injected to the CDN is adjusted incrementally until the voltage level measured at the 150Ω to 50Ω adapter (ADA-515-2) connected to the EUT port is approximately equal to the Umr value given in the table below. The ADA-515-2 and accessories needed for this test are available from Com-Power.
