Anti-islanding Relay HRN-100

Anti-islanding relay HRN-100

Used in three-phase electrical installations for monitoring and control or anti-islanding in renewable energy production installations.

- Supply voltage (V): 400

- Voltage type: AC

- Connection with three or four conductors (with or without neutral).

- Optionally monitors high and low voltage and frequency in three-phase circuits.

- Allows monitoring of failure, sequence and phase asymmetry including lack of neutral (only for 4-wire connection).

- Both output contacts can be set individually.

- Measures true RMS value of AC voltage (True RMS).

- Optional setting of output contact response delay to measured error state or transition from error state to OK state. Possibility of delayed response of the output contacts after connecting to the power supply.

- Possibility of automatic or manual transition from error state (memory).

- Optional closing or opening of the output contact when measuring an error condition (Fail Safe / Non Fail Safe).

- Password protection against unauthorized changes to settings.

- Backlit digital display with the ability to monitor the current state of the network, including possible faults.

- The last five error states are stored in a history that can be viewed retrospectively.

- Sealable transparent cover for display and controls.
