isoPV425-D4 + AGH420 Isometer

Isolationsüberwachungsgeräte für Photovoltaik

Product description

The ISOMETER of the isoPV425 series monitors the insulation resistance of unearthed AC/DC main circuits (IT systems) AC, AC/DC 0...690 V or DC 0...1000 V.


The DC-fed components in AC/DC systems have no influence on the response behavior. The separate supply voltage also makes it possible to monitor the de-energized system. The maximum permissible system leakage capacitance is 500 µF.


Main features:

- Insulation monitoring device for AC and DC IT systems

- Application Photovoltaic systems up to AC 690 V/DC 1000 V

- Separately adjustable response values 1 kΩ...1 MΩ

- Automatic adaptation to the grid leakage capacitance up to 1000 μF

- Measurement of mains voltage (RMS) with undervoltage/overvoltage detection


Features and functions:

- Insulation monitoring for unearthed systems AC, AC/DC 0...690 V, DC 0...1000 V

- Measurement of the nominal system voltage with undervoltage/overvoltage detection

- Measurement of mains to earth voltages (L+/PE and L-/PE)

- Measurement of the mains leakage capacitance

- BMS interface

- Fault location message L+/L- via display and relay contacts

- Automatic adjustment to mains leakage capacitance up to 500μF

- Supply voltage range DC 24...240 V/AC 100...240 V

- Self-monitoring and connection monitoring mains/earth with automatic message

- Indicator LEDs for operation, alarm 1 and alarm 2

- Internal/external test/reset button

- Two alarm relays with common root (one NO contact each)

- Working/quiescent current selectable

- Fault memory selectable

- Multifunctional LC display

- Adjustable response delay

- Compact 2-module housing (36 mm) plus coupling in 2-module housing

- Quick wiring with spring terminals


Technical features:

- Rated voltage AC 0...793 V, DC 0...1100 V

- Supply voltage AC 70...300V / DC 70...300V

- Dimensions ISO-PV W 36 x H 90 x D 70.5 mm

- Dimension AGH-420 W 36 x H 90 x D 70.5 mm
