ZFxxxI is a ultra-high precision DC current transducer that can continuously measure DC current up to ±600A. ZFxxxI also can measure AC current. The primary current is transformed into a proportional secondary current with a 1000:1 ratio. In addition, ZFxxxI has many advantages, such as excellent linearity, ultra-high precision, and low noise.
