BA Series Open Current Transformers
The BA series split-core products utilize the principle of electromagnetic induction for real-time AC current measurement in power grids. Using constant current and linear compensation technology, they isolate and convert the measured current into a standardized DC signal. Thanks to their safe operation with 12 V or 24 V DC, they are suitable for a wide range of applications in industrial automation.
