Frequency transducer
Output (DC) single or dual
Accuracy 0.5%
The input frequency signal is scaled down through Interposing potential transformer. The scaled down signal is fed to a precision frequency to voltage Converter stage, its output is processed to provide DC Voltage/ Current proportional to Line Frequency.
