Product Description

The GREWIN TAD series of current transformers for electronic watthour meters with DC-tolerance are designed for applications where AC current signals or half wave rectified DC current signals must be transformed accurately into a lower current signal appropriate for micro-processor based circuits. A new TA model can be designed and manufactured to meet the specific design challenges of the client's specific application. The following models are only a small sampling of the many different products which have been and are currently being manufactured.



 GREWIN MINI PRECISION CURRENT RANSFORMER
