The open-closed type AC Transmitter is a kind of DC4~20mA( Through 250KV) which can directly convert the AC current of the main circuit to linear proportion Ω Resistance conversion DC 1~5V or through 500V Ω Resistance conversion (DC1~10V) constant current ring standard signal measuring instrument, AC current transmitter has the advantages of high precision, fast response, small volume, low power consumption, wide frequency response, anti-interference, lightning wave and shock wave protection.
