The FP-COMB 63/1500-1 | 125/1500-1 | 200/1500-1 coupling/decoupling networks from HAEFELY are fully compliant with the standard requirements of IEC/EN 61000-4-4, IEC/EN 61000-4-5, IEC/EN 61000-4-12, as well as testing for compliance with the surge requirements of ANSI/IEEE C62.41 and others. They have been developed to enable users to efficiently set up and perform tests in conjunction with the expandable immunity test systems of the AXOS series - AXOS 5 and AXOS 8 - in a compact system.
The CDNs in this series are among the few devices that integrate the IEC/EN 61000-4-12 and ANSI C62.41 & C62.45 standards as standard in a single device.
The coupling networks are controlled by Haefely's AXOS 5 or AXOS 8 immunity test systems and automatically change the coupling paths, phase angles, and source impedance depending on the test parameters set by the user on the AXOS test system, such as the standard and coupling mode.
The FP-COMB 63-125-200/1500-1 CDNs were developed to reduce residual voltage levels by integrating the correct decoupling inductors for each type of CDN application in order to meet the requirements (in terms of voltage drop at rated current).
With a voltage of up to 1000 Vrms AC and up to 1500 V DC, and depending on the device, 63 A / 125 A or 200 A test object current per phase, the CDNs meet the highest requirements and guarantee user-friendly handling:
- Easy to operate - The integrated LEDs indicate which mode and path is active.
- Automatic - The surge impedance is selected automatically.
- Remote controlled - They can be fully remote controlled via the AXOS 5 / AXOS 8.
