Description

The open-close type AC transmitter is a kind of DC 4, 20 MA (through 250 kV) which can directly convert the AC current of the main circuit to linear proportional output 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.
