Undetected insulation faults in non-earthed networks may lead to accidents with considerable personal injuries and property damages. Monitoring of IT networks by insulation monitors is therefore normatively mandated. The insulation monitor LK 5896 from the VARIMETER IMD series by DOLD was developed especially for use in modern power supply systems.
These often include inverters, rectifiers, thyristor controllers and directly connected direct current components. Because of EMC interference suppression measures, high discharge capacities against earth are often present in these systems. The LK 5896 meets these requirements. It is suitable for network discharge capacities up to 3000 μF as well as for voltages up to DC...
