AGH-PV-3 Bender

The Bender AGH-PV-3 is an insulation monitoring device for unearthed AC, AC/DC, and DC systems (IT systems) used in photovoltaic plants up to AC 793 V/DC 1100 V. It is designed to ensure the safe and reliable operation of photovoltaic systems by continuously monitoring the insulation resistance between the live conductors and ground. The AGH-PV-3 features a range of advanced functionalities, including:

• Two separately adjustable response values: The alarm and warning thresholds can be set independently to suit the specific requirements of the photovoltaic system.

• Various AMPPlus measurement methods: The AGH-PV-3 supports a variety of measurement methods to ensure accurate and reliable insulation monitoring, even in challenging conditions.

• Automatic adaptation to system leakage capacitance: The AGH-PV-3 can automatically adapt to the leakage capacitance of the photovoltaic system, ensuring optimal performance regardless of the system size or configuration.

• Info button for displaying device settings and system leakage capacitance: The AGH-PV-3 provides an easy-to-use interface for displaying device settings and system leakage capacitance, allowing for quick and easy troubleshooting.

• Self-monitoring with automatic alarm: The AGH-PV-3 continuously monitors its own health and will automatically trigger an alarm if a fault is detected.

• Automatic self-test, selectable: The AGH-PV-3 can be configured to perform a self-test at regular intervals to ensure that it is functioning properly.

• Connection for external kΩ indication: The AGH-PV-3 can be connected to an external indicator to display the insulation resistance in real time.

• Test and reset button: The AGH-PV-3 features a test and reset button that can be used to manually initiate a test or reset the alarm.

• External test/reset button can be connected: An external test/reset button can be connected to the AGH-PV-3 for remote operation.

• Two separate alarm relays with two potential-free changeover contacts: The AGH-PV-3 provides two separate alarm relays that can be used to trigger external alarms or initiate other actions in the event of a fault.

• N/O or N/C operation, selectable: The alarm relays can be configured for normally open (N/O) or normally closed (N/C) operation.

• Backlit LC display: The AGH-PV-3 features a backlit LC display that is easy to read in all lighting conditions.

• RS-485 interface: The AGH-PV-3 includes an RS-485 interface for communication with a monitoring system or other devices.

• Presetting for PV systems via menu: The AGH-PV-3 comes with pre-configured settings for photovoltaic systems, making it easy to set up and use.
