CR Magnetics has a wide selection of Current Potential Transformers to
extend the range of any part. See Sections G & H for details.
Data Stream RS485 Digital Current Transducer
The CRD4100 Series Data Stream Digital Current Transducers
are designed for applications where AC current waveforms are
not purely sinusoidal.
The digital technology is used to measure voltage, current, power frequency and energy in single and three phase
designs. The data is streamed over an RS485 IEEE bus which enables
multiple transducers to communicate thru a single master connection.
These advanced sensors are ideal for entire plant or zone monitoring.
Also, the communication alagorithm can be pre-ordered with ASCII
based control or modified MODBUS based control.
