Onset HOBO T-MAG-SPT-300 [T-MAG-SPT-300] 300 Volt AC Potential Transformer Sensor, 230VAC

The Magnelab 600-Volt AC Potential Transformer is 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.
