Victron Anti-islanding relay:


The UFR1001E monitors voltage and frequency in plants for own generation of electricity. It fulfills 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 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 feed-back 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 availability of 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.


Features:

- Under and overvoltage monitoring 15…520 V

- Measuring phase-neutral or phase-phase

- Monitoring of under- and overfrequency  45…65 Hz

- Monitoring of quality of voltage (10-minutes-average)

- Monitoring of vector shift  2…65°

- Monitoring of rate of change of frequency (ROCOF, df/dt) 0,100...5,000 Hz/s

- One-fault-proof with monitoring of connected switches (defeatable when using the integrated switch of pv and battery inverter acc. to DIN EN 62109 (VDE 0126-4))

- 2 automatic restarts at error

- Passive anti-islanding protection acc. to ch. 6.5.3 and app. D2

- Switching delay adjustable 0.05 … 300 s

- Switching back delay adjustable 0 … 6.000 s

- Alarm counter for 100 alarms (trip value, cause and rel. time stamp)

- Record of added times of alarms

- Input for standby with counter and recording of time

- Test button and simulation with measuring of switching-times

- Sealing; All values can be read-out when sealed

- Easy installation and programming with pre-set programs

- Housing for DIN-rail-mount, 105 mm wide, mounting height 66 mm
