Product description:
I. overview
Alternating current (voltage) is a transmitter can be measured AC current (voltage) into the instrument according to the linear ratio of the output DC voltage or DC current, widely used in electric power, telecommunications, petroleum, coal, metallurgy, railway, municipal and other departments of the electrical device, automatic control and scheduling system.
AC current and voltage transmitter have single -, three - way combined structure:
1, high accuracy (typical: 0.2% best 0.05%).
2, the entire range has a very high linearity.
3, a high degree of integration, simple structure, excellent temperature characteristics and long-term stability of the work, so that the transmitter from the regular calibration.
