Open Source Meter Inc, offers a convenient true RMS to 4-20mA transducer solution to connect to high quality and accurate Split-Core and Solid-Core current transformers. This solution offers the best of both words- ease of installation and a wide range of current transformers.
Magnelab Split-core current transformers "sense" AC current from 5 to 5,000 Amps passing through the center conductor. Split-core transformers are ideal for installation on existing electrical wiring by snapping around the conductor.
The Magnelab SCT series have one of the highest industry standards both for interleaving joints and the self-locking mechanism.
Accuracy of Magnelab current transducers are within one percent of AC measurements.
