The HV high-power EFT/burst immunity test system EFT/500G& EFTN 15100T is a high-end test device, which is specially designed to meet the requirement of new energy test system and EUT with high-power load. The system features high reliability, stable performance and convenience to use. Its built-in coupling/decoupling network can couple maximum 4.8 kV pulse voltage onto mains supply system with voltage up to DC 1500 V/AC 700 V (three-phase-five-line) and current 100 A. Higher voltage and current levels are available for customer's request.
Features：
