Product Description

The GREWIN series Miniature voltage transformers are designed for applications where AC voltage signals must be transformed accurately into a lower AC voltage signal appropriate for micro-processor based circuits. The TAXX7X series of Zero-flux miniature voltage transformers are sampling transformers designed specifically for high quaity measuring instrument,It doesn't need any compensating measure,Which require exceptionally accurate primary signal transformation and insolation. YUANXING can designe and manufacture 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.
