T-VP Separately Powered Voltage Transducers T-VP Separately Powered Voltage Transducer

The T-VP 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 units is derived from an external source.
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.

Ordering information: T-VP, input, output, power supply.
Examples: T-VP, input 0-150Vac, output 4-20mA, supply 110Vdc.
T-VP-DSW dual slope, input 0-80-140Vac, output 0-1.2-10V, supply 230Vac.
T-VPW window, input 90-130Vac, output 4-20mA, supply 110Vdc
