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
