Current transducers are electrical devices that measure the current of an electrical system with a non-contact method. They are used for precise monitoring and control of electrical loads. CR9350-PNP-M is one of the current transducers which can measure current in both AC and DC modes in an integrated solution with an Arduino and other development boards.The CR9350-PNP-M includes an integrated current-sensing resistor, an inductive sensing element, and a low noise aluminum electrolytic capacitor for reliable current measurements up to 30 Amps in both AC and DC modes. The current measurements are made by the sensing resistor converting the current into the voltage which is then fed into an operational amplifier and buffered by the SiS-817 opamp. The operational amplifier output voltage is then converted to a digital output signal.The CR9350-PNP-M is designed with two mounting holes, making it easy to install. The 3.3V and 5V supply connections are provided on the PCB for the current transducers. The DC supply voltage should not exceed the 3.3V and 5.0V voltages.The sensing elements used in CR9350-PNP-M provide a high CMR which ensures a high accuracy measurement of the current flow. In addition, the sensing resistor and inductive sensing element give a linear response over the whole operating range and require no additional calibration. The measurement range of the CR9350-PNP-M is 0-30A with a 1mA resolution.The CR9350-PNP-M has a low self-consumption of around 8mW when measuring current, making it very efficient. It also features a fast response time of less than 5 ?s. The high isolation voltage of up to 8kVrms and low EMI emission guarantee the accuracy, reliability, and safety of the measuring system, making it suitable for most industrial applications.In terms of usage, the CR9350-PNP-M can be used to measure motor current, battery current, solar panel current, etc. It can also be used to monitor the current, and display the values on an LCD or OLED display.Overall, the CR9350-PNP-M current transducer is a versatile, reliable, and accurate solution for current measurements up to 30 Amps. With its application field and working principle, it provides an effective and reliable current measurement system for industrial applications.
