CWS 500N3 - TESTING OF RIPPLE NOISE AND MAGNETIC FIELDS

Key applications of the CWS 500N3 are in the automotive and aerospace area. Various international standards and MIL requirements call for magnetic field tests in the low frequency range. Apart from this the automotive industry requires conducted immunity tests with superposed sinusoidal signals on the DC supply voltage (ripple noise). For both applications the CWS 500N3 is the perfect equipment including everything in a single box, necessary for these tests. The CWS 500N3 meets requirements of SAE J1113-2, ISO 11452-8, DO 160D/E Section 18 and MIL-STD-461 D/E CS101, CS109 and RS101.
