Further Details
The W 443 enables high-end test features at a value price for the test of safety-related cable harnesses in the aerospace, transportation and automotive industries. As a result of the cle- ver combination of powerful measurement technology, constant current sources up to 3 A and high voltage sources up to 2,250 Vdc, the W 443 can be used without any restriction for high voltage test stations according to EN 50191.
Typical values, valid at the front panel of the tester without adaptation at 25° C and a relative humidity less than 60 %
