DC insulation monitor ISOMETER® isoBAT425

RS485Modbus RTU

Insulation monitoring device for battery production According to IEC 61557-8 Multifunctional display Localisation of fault location (L+ or L-) Batteries up to DC 400 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 Features Monitoring of the insulation resistance RF to earth Monitoring of the battery voltage Un between terminals L+ and L- Measurement of the voltages UL+e and UL-e of terminals L+ and L- to earth Determination of the fault location (%), i.e. the distribution of the insulation resistance RF between terminals L+ and L- Monitoring and automatic adjustment to the system leakage capacitance up to 1 μF Continuous connection monitoring of terminals L+, L- and E Selectable start-up delay, response delay and delay on release Two separately adjustable response value ranges of 10 kΩ …5 MΩ (alarm 1, alarm 2) Configurable measuring frequency for adjustment to the physical characteristics of the battery Alarm signalling via LEDs (AL1, AL2), display and alarm relays (K1, K2) Automatic device self test
