Com-Power CDN-M350E 150 kHz to 230 MHz Coupling Decoupling Network

The CDN-M350E series is for used for testing products with three wire power supply lines (L +N + PE). It can handle up to 50 A (AC) or 35 A DC power source. It has 5.2 mm shrouded banana socket for both EUT and AE power connection. The RF disturbance signal is injected using a BNC connector which can handle up to 40 V of input. The bottom surface of the CDN is not painted, so that it be properly grounded during the test.

All Com-Power CDNs can be purchased separately or part of the CIS series conducted immunity test system. The test system includes the ACS series power amplifier and accessories required to conduct the immunity testing. All Com-Power CDNs are individually calibrated.The Com-Power CDN-M350E fully complies with the requirement contained in the IEC 61000-4-6 and CISPR 16-1-2.

ring 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-M350E 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.

Umr= Voltage level measured at the output of the 150Ω to 50Ω adapter (ADA-515-2)
