The premier choice for high-end test parameters of cable assemblies and components for the aerospace, military, medical and transportation industries. The W 454 features high voltage up to 4,400 VDC and 3,200 VAC, as well as current up to 3 A. This system can distribute test points in smaller external matrix cases and offers adapter cable ID for instant recognition of device under test (DUT) insertion. Functional testing of program power, electronic controls and sub-assemblies is available.
