High Voltage Cable Test Solution - W484

Especially for the testing of high voltage cable harnesses and components for electric and hybrid vehicles, WEETECH has developed the new W 484 Test System. It meets the requirements of the industry standard LV 123*. The high voltage source with voltages up to 4,300 Vdc / 3,000 Vac is current limited to a maximum of 3.8 mA and considered as safe to touch according to DIN EN 50191.

With the compact W 484 Test System, continuity measurements in the µOhm range as well as insulation measurements in the GOhm range are possible. Three integrated innovative detectors react fast reliable on insulation failures. Optionally, adapter cables equipped with ID chips can be connected to any output connector on the system.
