Universal electronic maximum minimum voltage relay
APPLICATIONS
The RN-112 universal electronic maximum/minimum voltage relays are designed to monitor allowable voltage value and voltage presence with rated parameters 100V/ 50Hz as well as to switch electric curcuits in protection and automation devices of electric installations where the nominal voltage is above 1000V.
The relay provides adjustments of trip settings for voltage and time delay when voltage threshold values are reached. The relay provides three modes of operation:
- the minimum voltage relay mode (the relay trips only when the minimum voltage threshold is reached);
- the maximum voltage relay mode (the relay trips only when the maximum voltage threshold is reached);
- the symmetry settings mode (the relay trips when both the maximum and the minimum voltage thresholds are reached).
