Overview S3 (T) -VD-3 transmitter is able to be measured by the AC voltage signal isolation amplifier, converting the input voltage into a DC voltage or current amount of the instrument is linearly proportional to the output, which is widely used in power systems and non-electrical systems, long-term continuous operation, realize the measurement of the amount of the AC voltage. Features S3 (T) -VD-3 Transmitter The series of high accuracy, good conversion performance, good temperature characteristics, have lightning protection. S3 (T) -VD-1T (N3-VD-1T), S3 (T) -VD-3T (N3-VD-3T) type transmitter, the input signal waveform distortion does not affect the measurement accuracy of the instrument. With a long-distance transmission capacity (4 ~ 20mA, 500Ω), fixed way, in line with DIN46277, according to the 35mm mounted on aluminum rails.
