100 AMP Split-core AC Current Transformer Sensor

Part # T-MAG-SCT-100
Lead Time: 3-4 Weeks
1.25” Opening


The Magnelab AC Current 100 Amp AC Current Transformer or CT (Magnelab part # SCT-1250-100) is mounted around a current carrying wire to measure AC Amperage. This CT provides 333mV output proportional to current and is used with the FlexSmart TRMS Module for True RMS measurement of sinusoidal and non-sinusoidal waveforms. The result is accurate current measurement for many types of equipment, including variable frequency drives and switched power sources. One or two CTs can be used with each FlexSmart TRMS Module.
