Unit BU1-DC2 is equipped with an over (U>) and under voltage supervision (U<) with separate adjustable pick up values and common trip delay (t) and hysteresis (DIFF).
The DC voltage measured is constantly compared with the set reference values. Any voltage signal, which exceeds the set reference value for over voltage, or falls below the set reference value for under voltage, will cause the respective relay to trip after elaps of the time delay.
