The Split Core Current Transformers are designed to convert an AC operating current into a low voltage AC signal for use with microprocessor based circuits that require maximum accuracy and precision. All of the Split Core CTs come standard unterminated with ferrules for easy connection to any of the Single or 3 Phase Dent power meters. Any of the split core CTs can be used with any of the Powerscout™ PS3037, PS24, PS12HD, PS48HD Power Meters in applications where typical power measurements are required and reduced accuracies are acceptable. Where higher accuracies are required, refer to the Revenue Grade CTs product data sheet for more detailed product information.
