Overview
Surge pulses occur due to direct or indirect lighting strokes to an external circuit. This leads to current or electromagnetic fields causing high voltage or current transients. Another source for surge pulsed is switching transients originating from switching disturbances and system faults. Nearly every electrical and electronic device may suffer from such surge pulses. CWS series is a high-end test instrument which fully complies with CE and CCC relative standards.with external CDN and optional accessories, it can conduct for three-phase DUT and also pulsed magnetic field immunity test. For CWS X00G/SPN38XXT, X stands for voltage in CWS X00G and X stands for network load current capacity in SPN38XXT.
