ISOMETER® isoBAT425 with coupling impedance ZE420

ISOMETER® isoBAT425 with coupling impedance ZE420

  • Insulation monitoring device for battery production
  • According to IEC 61557-8
  • Multifunctional display
  • Localisation of fault location (L+ or L-)
  • Batteries up to DC 500 V

This ISOMETER® is intended for monitoring the insulation resistance as well as the voltage of a battery during its assembly from individual battery cells. The ISOMETER® monitors the insulation resistance of batteries with nominal system voltages of DC 0…400 V. The maximum permissible system leakage capacitance Ce is 1 μF. The resulting measured values allow diagnosing the type and location of the insulation fault.

In order to meet the requirements of applicable standards, customised parameter settings must be made on the equipment in order to adapt it to local equipment and operating conditions. Please heed the limits of the area of application indicated in the technical specifications
