Data acquisition system
The data acquisition system of protection system is composed of 14-bit precision A/D converter with high
reliability, multiplexers switch and filter circuit. Inside A/D conversion chip with the latest technology, there are
sampling hold and synchronous circuit, which has the advantages of rapid conversion speed, low sampling error,
very little power consumption and excellent stability. Therefore, there is no adjustable component for sampling
circuit, and there is no need to adjust in the field, and the device has excellent reliability.
