FEATURES
■Accuracy: ± 0.025% RO.■Self powered■Exnt long term stability (4 ~ 20mA, 500 W )■High impulse & surge protection (5KV)■The case can be mounted on a 35mm rail which complies with DIN 46277
DESCRIPTION■Model: S3-FD : Accuracy：0.2%RON3-FD: Accuracy：05%ROS3-FD transducer to measure power frequency and provide a DC output directly proportional to the change of input within the specified span. The input pan>is shapped to square wave by the wave shappers circuit. The duty cycle of the square wave is change with the frequency of the input span>Then the square wave is fed into an integrated circuit and the produced DC output is proportional to the input frequency.
