HRN-100
Description
HRN-100 | Multifunction voltage monitoring relay in 3P with LCD display
- 3-wire or 4-wire connection (with or without neutral).
- Optionally monitors high and low voltage & frequency in 3-phase circuits.
- Allows monitoring of failure, sequence, and phase asymmetry incl. neutral failure (only for 4-wire connection).
- The product is powered by a monitored voltage.
- Both output contacts can be set individually.
- Measures the true RMS value of True RMS.
- Optional setting of output contact response delay and measured error condition incl. Possibility of delayed response of the output contact after power supply connection.
- Possibility of manual or automatic (default setting) 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.
- Digital backlit display with the ability to monitor the current state of the network incl. possible failures.
- The last five error states are stored in a backed-up history that is possible to view
- Sealable transparent cover for display and controls.
