BU1-AC AC Voltage Relay
Application
Over and under voltage supervision of 1 and 3 phase systems.
Function
Unit BU1-AC is eguipped with an independent over {U>) and under voltage supervision {U<) with separate adjustable pickup values and common trip delay {t) and hysteresis {DIFF). The voltages are compared with the set reference values.
For three phase over voltage supervision the highest voltage in each phase is evaluated, for under voltage supervision the lowest in each phase.
Pickup of supervision circuit U> or U< is indicated by flashing of the corresponding LED.
At U< tripping LED U< extinguishes, at U> tripping. LED U> is steady lit.
At voltages < 60 % Un no trip delay takes place.
