Three-phase system insulation monitor ISOMETER® iso685-…-B series

for AC networksAC/DCDC

• Predefined measurement profiles • Reliable measurement of insulation resistance, voltage, capacitance and frequency • Integrated web server • Modbus TCP/RTU • Can be used in coupled IT systems The ISOMETER® is an insulation monitoring devices in accordance with IEC 61557-8 for IT systems. The devices are 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). Device variants iso685-D: This device variant ISOMETER® iso685-D features a high-resolution graphic LC display and operating controls for direct operation of the device functions. It cannot be combined with an FP200. iso685-S: This device variant ISOMETER® iso685-S features neither a display nor operating controls. It can only be used in combination with the FP200 and it is operated via this front panel. Option "W": The ISOMETER®s with and without integrated display are available with option „W“ for extreme climatic and mechanical conditions (ISOMETER® iso685W-D and iso685W-S). Features • ISOMETER® for IT AC systems with galvanically connected rectifiers or inverters and for IT DC systems (IT = unearthed systems) • Automatic adaptation to the existing system leakage capacitance. • Combination of AMPPlus and other profilespecific measurement methods • Two separately adjustable response value ranges of 1 kΩ…10 MΩ • High-resolution graphic LC display for excellent readability and recording of the device status • Connection monitoring (monitoring of the measuring lines) • Automatic device self test • Graphical representation of the insulation resistance over time (isoGraph)
