CWS 500N4 - TESTING FOR IMMUNITY TO CONDUCTED, COMMON-MODE DISTURBANCES
The CWS 500N4 is the state-of-the-art solution in a compact single-box design to test for immunity to conducted, common
mode disturbances in the frequency range 0Hz (DC) to 165kHz. Such test requirements are specified in IEC 61000-4-16 and
cover continuous mode testing as well as short term testing with DC, 16 2/3Hz, 50Hz and 60Hz with 4 test levels each plus a
sweep mode from 10Hz to 165kHz.
Additionally, the CWS 500N4 can be used for testing electricity metering equipment as per prTR 50579 and Draft standard
IEC 61000-4-19, Annex C.
