AC/DC insulation monitor ISOMETER® isoPV1685DP

DCRS485Modbus RTU

For large photovoltaic systems up to AC 1000 V / DC 1500 V 2 Separately adjustable response values 200 Ω...200 kΩ Automatic adaptation to the system leakage capacitance up to 4000 μF Modbus RTU interface for connection to monitoring systems User-friendly operation through integrated display The device is used for insulation of large photovoltaic systems up to AC 1000 V/DC 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 up to 4000 µF against earth exist due to interference suppression methods. Features Automatic adjustment to very high system leakage capacitances up to 4000 µF Special measuring method ideal for DC systems in combination with 50 Hz / 60 Hz systems Separately adjustable response values Ran1 (alarm 1) and Ran2 (alarm 2) for prewarning and alarm High-resolution graphic LC display for excellent readability and recording of the device status Connection monitoring Automatic device self test with automatic alarm message in the event of a fault Graphical representation of the insulation resistance over time (isoGraph) History memory with real-time clock (buffer for 13 days) for storing 1023 alarm messages with date and time Freely programmable digital inputs and outputs Remote setting of certain parameters via the Internet (COMTRAXX® gateway) Remote diagnosis by the Bender service via the Internet RS-485 interface for data exchange with other Bender devices
