LP-VPW Window & LPVP-DSW Dual Slope
The LP-VPW & LP-VP-DSW voltage transducers convert an ac voltage input into an output signal which is proportional to the rms calibrated arithmetic mean of the input.
Accurate measurement assumes a sinusoidal input waveform.
To enhance the resolution of the reading the transducer can be set up to operate with an input window or a dual slope output.
The window option suppresses the lower end of the range so that the transducer reads over a band of voltage centred on the nominal working voltage of the system being measured.
The dual slope option has a lower resolution at the low end of the range with a higher resolution centred on the nominal working voltage of the system being measured.
Power for the units is derived from an external supply.
