Multifunction voltage monitoring relay in 3P with LCD display
Start of sales: March 2021
Multifunction and in many ways universal monitoring relay which protects devices and equipment connected to a 3-phase network.
Description
-
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 fi ve error states are stored in a backed uphistory that is possible to view
-
Sealable transparent cover for display and controls.
