Description
- 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.
- Two adjustable levels of frequency (Fmin, Fmax) in the range of 80 – 120 % Fn.
- Adjustable difference level.
- Adjustable delay level.
