Voltage transducer
Input AC voltage
Output (DC) single or dual
Accuracy 0.5%
The input Voltage signal is scaled down through Interposing potential transformer. The scaled down signal is fed to a precision rectifier stage, its output is processed to provide DC Voltage / Current output proportional to input AC voltage. The output signal is calibrated for RMS value.
