Victron Anti-islanding relay Ziehl UFR1001E

The Ziehl UFR1001E monitors voltage and frequency in plants for own generation of electricity. It fulfils the requirements of VDE-AR-N 4105 bdew-directive, G59/3, G83/2 and ÖVE/ÖNORM E 8001-4-712:2009 for generators connected to the public grid.

The function of the output-relays and of the connected switches can be monitored with feedback contacts. When a connected switch does not switch off, the UFR does not switch on again. When a switch does not switch on it makes 2 restarts and thus improves the availability of the monitored plant.
