Damped-Oscillatory Wave Simulator SWCS-900 series

Damped Oscillatory Wave Simulator (SWCS) Damped-Oscillatory Wave Simulator　SWCS-900 series

Damped-Oscillatory Wave Simulator simulates and generates the fast, repetitive high-frequency noise generated when switches and other switching devices turn ON/OFF, evaluating the immunity of electronic and electrical equipment. The SWCS-900-1M can perform tests compliant with the Japanese power standard B-402 (2007) and the IEC 61000-4-18 (Ed. 1.0) standard.
