For testing high-voltage cable harnesses and components for electric and hybrid vehicles, the system W 484 was developed. It meets the requirements of the LV 123* industrial standard. The high-voltage generator HVG 4300 delivers voltages of up to 4,300 Vdc/3,000 Vac and is current-limited to a maximum of 3.8 mA. This makes the W 484 harmless according to DIN EN 50191. Optionally, an HVG 4300-12 with currents of maximum 12 mA can also be used.
Resistance measurements in the µOhm range, insulation tests in the GOhm-range as well as a highly developed ARC detection enable a flexible use also in other areas.
The W 484 PLUS also provides cost-optimized LV-test points for test benches and adaptation modules that can be used as LED, detection or power points. The test system is compatible with all adaptation tables available on the market and meets their technical requirements.
