Description

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：

  • EUT DC load capacity: DC 1500 V 100 A.
  • EUT AC load capacity: AC 700 V 100 A, three -phase five- wire.
  • EUT power automatic switching over.
  • EUT voltage and current detection.
  • Overvoltage, over-current protection.
  • Setting test voltage, polarity and phase sync angle by scheduling and fully automatic network switching over.
  • Phase angle superposition for any line.
