Frequency monitoring relay
•
the relay serves to monitor frequency of AC voltage, e.g. in photovoltaic power
stations, generators
•
the monitored frequency 50 / 60 / 400 Hz is selected by a switch
•
supplied from monitored voltage
•
two adjustable levels of frequency (Fmin, Fmax) in the range of 80 - 120 % Fn
•
adjustable diff erence level
•
adjustable delay level
•
switchable ranges of rated frequency Fn
•
3-MODULE design, DIN rail mounting
