Page 18: Delayed Trip
To guarantee a sufficient resolution for the current set values, a nominal current adequate to the application should be selected. iseg offers HV modules with nominal currents reduced to 100 μA in all voltage classes. These are designated e.g. for semiconductor detectors, which only require a few microampere operating current. -
