Three Phase Self Power High AC Current Transducer
This device is a self power 3-element high AC current isolation transducer. Adopts the principle of electromagnetic isolation, can sample the high AC current, and isolated output 0 ~ 10V standard signal. The inputs and outputs are electrically isolated from each other, completely linear relationship between the input signals and the output signals. Can be widely used in motor current real-time detection/monitoring, and motor starts over current protection system. Wide application in the coal mining machine, excavators and other large mechanical electrical current testing.Data Sheet
