LP-VP Separately Powered &
LP-VL Loop Powered Voltage Transducers

The LP-VP and LP-VL voltage transducers convert an ac voltage input into an output signal which is proportional to the rectified arithmetic mean of the input.
Accurate measurement assumes a sinusoidal input waveform.
Power for the unit is derived from an external supply.

Ordering information: LP-VP, input, output, power supply. LP-VL, input.
Examples: LP-VP, input 0-250Vac, output 0-10mA, power supply 230Vac.
LP-VL, input 250Vac
