ISOMETER® isoPV425 met AGH420
- Isolatiebewakingsapparaat voor AC- en DC-IT-systemen
- Applicatie fotovoltaïsche installaties tot AC 793 V/DC 1100 V
- Automatische aanpassing aan de netontladingscapaciteit tot 1000 µF
- Hoofdrelais voor bediening van meerdere ISOMETERs® in gekoppelde IT-systemen
The ISOMETER® of the isoPV425 series monitors the insulation resistance of unearthed AC/DC main circuits (IT systems) with nominal voltages of 3(N)AC, AC, AC/DC 0…690 V or DC 0…1000 V.
DC components existing in AC/DC systems do not influence the operating characteristics. A separate supply voltage allows deenergised systems to be monitored as well. The maximum permissible system leakage capacitance is 1000 µF.

Kenmerken
- Monitoring for unearthed AC and DC systems with galvanically connected rectifiers or inverters
- Measurement of the nominal system voltage Un (True RMS) with undervoltage and overvoltage detection
- Measurement of DC voltages system to earth (L+/PE and L-/PE)
- Automatic adaptation to the system leakage capacitance up to 1000 μF
- Automatic device self-test with connection monitoring
- Selectable start-up delay, response delay and delay on release
- Two separately adjustable response value ranges of 1…500 kΩ (Alarm 1, Alarm 2)

- RS-485 (galvanically isolated) including the following protocols:
– BMS interface (Bender measuring device interface) for data exchange with other Bender components
– Modbus RTU
– isoData (for continuous data output) - Password protection to prevent unauthorised parameter changes
Toepassingen
- AC, DC or AC/DC main circuits
- Solar systems with directly connected inverters
