Introduction

The CDN M2-200 Coupling/Decoupling Network is designed for high-power electrical equipment with a three-phase five-wire design. It enables reliable coupling of RF common-mode disturbance signals onto three-phase power lines and effective RF decoupling between the EUT and AE during EMC conducted immunity testing.

With a maximum load capability of 200 A, it is suitable for EMC compliance testing of power electronics, industrial control, renewable energy systems (photovoltaic and wind power systems), smart grids, and other high-power equipment.

Features

> 200 A/700 V AC and 1,500 V DC high load capability

> Meet both high load capability and standard impedance requirements

> 150 kHz ~ 230 MHz wide frequency range with stable performance

> Optimized for unshielded power line immunity testing
