ISOMETER® isoHV525

ISOMETER® isoHV525

  • Insulating monitoring device for unearthed AC, AC/DC, and DC systems (IT systems)
  • Installations up to 3(N)AC, AC/DC 0...1000V or DC 0...1000 V
  • Two separate selectable response values
  • Automatic adaptation to the system leakage capacitance up to 150 μF
  • Alternatively with analogue output or serial interface (BMS, Modbus RTU, isoData)
  • Degree of protection IP65

The isoHV525 ISOMETER® monitors the insulation resistance of unearthed AC, AC/DC and DC systems (IT systems) with nominal system voltages of 3(N)AC, AC/DC 0…1000 V or DC 0 …1000 V. The maximum permissible system leakage capacitance Ce is 150 μF.

DC components existing in AC systems do not influence the operating characteristics, when a minimum load current of DC 100 mA flows. A separate supply voltage allows de-energised systems to be monitored too.

Please heed the limits of the area of application indicated in the technical specifications. Any use other than that described in this manual is regarded as improper.

The isoHV525 is contained in an enclosure filled with polyurethane and can therefore be used under extreme environmental conditions such as shock, vibration and temperature.
