Overview
EM Test CWS 500N4 Description
The EM Test 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.

Benefits
The EM Test CWS 500N4 consists of all the necessary parts to perform full-compliant tests as per IEC 61000-4-16 including the signal generator, the LF amplifier, a DC rectifier module, a semiconductor power switch and the rms measurement of voltage and current.
The CWS 500N4 is able to generate all continuous mode test levels up to 30V (DC, 16 2/3Hz, 50Hz and 60Hz) and the frequency sweep 15Hz to 150kHz without any additional external voltage source.
In order to perform the short-term mode tests up to 300V (DC, 50Hz or 60Hz, depending on the mains line frequency) the optional MV 2606N2.2 is required.
If tests need to be done with 16 2/3Hz or at frequencies other than the mains line frequency the optional programmable AC voltage source ACS 500N2.2 is needed.
