W 454

The modular and flexible high voltage tester

The W 454 Cable Tester and Functional Tester offers high voltages up to 2,250 VDC / 1,500 VAC and current levels up to 3 A to test cables, cable harnesses, harnesses and components for example in the aerospace industry, in medical technology industry and in the railway industry.

This test system allows for continuity tests in the Milli-Ohm range, insulation measurements in the Giga-Ohm range as well as measurement of components like resistors, capacitors, inductors and relays.
