High anti-interference DC voltage transducer

This product is a digital isolation transducer for DC voltage acquisition and measurement . It can be used to measure the voltage in DC circuit. The ratio dynamic range can be up to 1000: 1 with a high-precision 24-bit dedicated AD chip. By using the resistive voltage-dividing and resistance sampling measurement principle, it has high accuracy, good stability and high communication speed, the completely isolated processing technology is with anti-interference ability.
