The measuring devices SEFELEC 56-H and 506-H from EATON allow dielectric strength tests to be carried out in AC and DC; Thanks to the DSP technology and the DUAL-ARM-Core architecture, a high level of stability and repeatability is achieved. The high accuracy and measuring speed are suitable for quality control or entry control departments. The sequence mode makes the SEFELEC 56-H and 506-H easier to use and integrate into a controller or test bench.
