TVA2/2-C miniature voltage transformer is designed for applications where AC voltage signals must be transformed accurately into a lower voltage signal appropriate for micro-processor based circuits. TVA2/2-C current-type voltage transformer is a kind of mA current transformer, which turn ratio between primary and secondary is similar to 1:1. a limiting resistor is nessary to be in it with primary winding.TVA2/2-Cis popular to a limited internal space of devices.
