The HOBO MAG-SPT Series AC Potential Transformers measure True RMS for accurate readings of sinusoidal and non-sinusoidal waveforms. Three measuring ranges are available including 150, 300, 600 Volts AC. The Magnelab Transformers are used with the FlexSmart TRMS Module to provide accurate measurement of AC voltage. One or two PTs can be used with each FlexSmart TRMS module. This sensor offers an accuracy of ±1% (from 10% to 130% of rated voltage), but because this transformers ties directly into the line, it should be used only by qualified personnel.
