Victron Energy REL100100000 Anti-Islanding Relay UFR1001E

Victron Energy Anti-Islanding Relay UFR1001E: The Ufr1001e Monitors Voltage And Frequency In Plants For Their Generation Of Electricity

It fulfills the requirements of VDE-AR-N 4105 blew-directive, G59/3, G83/2, and ÖVE/ÖNORM E 8001-4-712:2009 for generators connected to the public grid.

The UFR1001E is a dual-channel device and thus one-fault-proof. 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.

The limits are pre-set according to VDE-AR-N 4105-2011-08, VDE-AR-N 4105:2018-11, and other standards. They can be changed if required and be protected with a code and/or a seal.

With a 2-step test, both channels can be tested individually and the triggering time of connected switches is measured.

The standby input allows a remote shutoff e.g. with a RCR.
