The OSM-RMS333DCX.X is a 333mVrms (max input 1Vrms) to DC output transducer. The module is designed to work with standard 0-333mVrms current transformers, potential transformers, sensors, and many different types of panel meters. With its compact size, ultra low power requirements, and wide range of voltage inputs, it can be configured into many project designs with ease. The module comes preprogrammed for output values of 0.2, 2, 2.5, 3.3 and 5VDC. Custom output values with a max output between 0.2V to 5V can be ordered.


Open Source Meter Inc, offers a convenient true RMS DC 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 333mvAC 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.
