Data sheet.

LP-VS, LP-VSX3 Self Powered Voltage Transducers

The LP-VS voltage transducer converts an ac voltage input into a dc output signal which is proportional to the rms calibrated rectified arithmetic mean of the input.
Accurate measurement assumes a sinusoidal input waveform.
Power for the unit is derived from the input signal.

The LP-VSX3 consists of three independent LP-VS circuits in a single case.

Ordering information: LP-VS(X3), input, output.
Example: LP-VS, input 0-250Vac, output 0-10mA
