isoPV1685P-425 - INSULATION MONITORING DEVICE (DC 0-1500 V), μSD card , RS-485/BMS(Slave), (ALSO FOR EDS DEVICES) (4 - 6 εβδομ.)

ISOMETER® isoPV1685P
- Insulation monitoring device for DC IT systems
- Application photovoltaic systems up to DC 1500 V
- Separately adjustable response values 200 Ω…1 MΩ
- Automatic adaptation to the system leakage capacitance up to 2000 μF
- Interface RS-485/BMS

The device is used for insulation monitoring of large photovoltaic systems up to 1500 V designed as IT systems. The measurement method specially developed for slow voltage fluctuations (MPP-Tracking) monitors the insulation resistance even in systems equipped with large solar generator panels where extremely high system leakage capacitances against earth exist due to interference suppression methods. Adaptation to system-related high leakage capacitances also occurs automatically.

The device generates locating current pulses required for insulation fault location. That allows the localisation of the insulation fault using permanently installed or mobile insulation fault locators.
