Product Description
Instrument Current Transformer
Product description
This product is used as an electric energy metering device that requires high precision and small phase error. The input AC current through the core hole of the transformer induces a Ma-level current signal on the secondary side ,which is converted into the required voltage signal by the back-end sampling resistor and accurately transmitted to the electronic circuit based on micro-processing .
Product characteristics
Low price ,easy cost control
High precision ,wide linear range ,excellent consistency
Small size and light weight ,easy for high -density PCB mounting
Various shape structures are available
Application
Apply to monitoring of multi-function instruments, intelligent detection instruments ,electronic watt-hour meters and building control systems .
