NEW: VDE-AR-N 4120:2018-11, VDE-AR-N 4110:2018-11, VDE-AR-N 4105:2018-11

he grid- and plant protection device UFR1001E monitors voltage and frequency in plants for own
generation of electricity. It complies with the requirements of VDE-AR-N 4105:2018-11, VDE-AR-N 4110:2018-11, G98 and G99, ÖVE/ÖNORM E 8001-4-712:2009 and other standards 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.
