DESCRIPTION

Model:  S3-VD-1 -  Single Phase input (AVG)

            S3-VD-3 -  Three Phase input (AVG)

            S3-VD-1T - Single Phase input (TRMS)

 
 

Sinusoidal Waveforms -  AVG

            S3-VD Series Transducer converting a sinusoidal alternating voltage into a dc output, proportional to the RMS value of input.  These units are average sensing, but RMS calibrated for a sine wave with less than 1% distortion.  The input signal is converted to a dc voltage which then feeds to a single amplifier and a dc output produced.

Non-Sinusoidal Waveforms - TRMS

S3-VD-1T Transducer are designed for use on waveforms with up to 30% of 3rd harmonic content.  The input signal is fed to an RMS detection circuit and the resultant dc volts produced are a linear function of the RMS value of input waveform.  This dc voltage is converted to a milliamp output via an output amplification circuit.
