Description

Almost all electrical equipment and devices can be affected by the unidirectional surges caused by over-voltages from switching and lightning transients. CWS x00G/SPN xxT series is a particularly designed system for the surge immunity tests for three phase EUTs with automatic switching of external CDN, and can also be used for pulsed magnetic field immunity tests. The products are in full compliance with CE and CCC requirements. The series includes 6 kV & 8 kV generators CWS 600G & CWS 800G, and SPN with EUT load capacity: AC 380V or 450 V, & 16 A – 100 A or customizable.

Features

  • 5.7” color touch screen front panel operation.
  • Surge voltage up to 6 kV/8 kV, surge current up to   3 kA/4 kA.
  • Surge voltage/current monitoring on LCD display (optional).
  • Fault detection (optional).
  • Test sequencing, easy operation.
  • External automatic 3-phase 5-wire CDN.
  • Can be used for IEC 61000-4-9 tests with optional induction coils.
  • RJ45 for PC control & test report printing.
