Insulation Monitoring Device for IT AC systems with galvanically connected rectifiers and inverters and for IT DC systems with isoData for logging measurement events with ISOsync for capacitive coupled IT-systems Product description The ISOMETER® is an insulation monitoring device for IT systems in accordance with IEC 61557-8. It is universally applicable in AC, 3(N)AC, AC/DC and DC systems. AC systems may include extensive DC-supplied loads (such as rectifiers, inverters, variable-speed drives). Application • C, DC or AC/DC main circuits A • C/DC main circuits with directly conA nected DC...
