Insulation monitoring device for IT AC systems with galvanically connected rectifiers and converters and for IT systems especially for railway applications Product description The ISOMETER® isoRW685W-D is an insulation monitoring device for IT systems in accordance with IEC 61557-8 for railway applications and has been specifically tested according to DIN EN 50155. 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...
