The BSR-3-480-32 is an automated 3-phase coupler decoupler network (CDN) designed for electrical fast transients/burst and surge testing to IEC 61000-4-4 and IEC 61000-4-5. This equipment is limited to 3 x 480 VAC with a current rating of 32 Amps 50/60 Hz for the EUT. It provides coupling in accordance with EN/IEC 61000-4-4, EN/IEC 61000-4-5, and EN/IEC 61000-4-12 for burst up to 5.5kV, surge and ring wave to 7kV. This network can be rented with the EM Test NX7 series, or individually to supplement testing needs. This system comes standard with a current ISO 17025 accredited calibration and associated documentation. This CDN can be controlled via the immunity generator or through control software via PC.
