The TH0500 Precision Current Conversion Standard Series is designed for high-accuracy current measurement and calibration applications. Using advanced DC current comparator technology, the TH0500 converts nominal DC/AC currents ranging from 0.1 A to 20 kA into proportionally smaller voltage or current signals while maintaining exceptional ratio accuracy.

Available in both direct-connected and through-core configurations, the TH0500 delivers excellent frequency response performance and long-term stability, making it suitable for metrology laboratories, high-precision calibration systems, and industrial power equipment testing.

Applications

Current transformer (CT) calibration
Power equipment and relay protection testing
Precision measurement systems and metrology labs
Grid monitoring and instrumentation verification
Manufacturing quality control and R&D testing
