Voltage Transducer

The Voltage transducer STE-A-1T converts a sinusoidal AC Voltage signal into an output signal that can serves several receiving instruments such as indicators, recorders, alarm units etc. The input Voltage is scaled down using a Voltage transformer T. The output of the transformer is rectified and filtered in a precision absolute amplifier A, incorporating integrated circuits. The amplified filtered output is proportional to R.M.S value of the sine wave input. The output is fed to a current converter 'C' to provide a load independent D.C. Current.
