Current transducers are devices that measure electric current and convert the signal to a voltage that can be used in further measurement and control purposes. The CR4120S-25 is an example of a current transducer that does this. It has a wide range of applications in many areas and its working principle is straightforward.

The CR4120S-25 is designed to measure direct current (DC) up to a maximum of 25 amps. The device consists of two major components – a current transformer and an output amplifier – connected by a precision measuring cable. The transformer is designed to pick up and amplify the current passing through the conductors in the cable, while the amplifier converts the current signals to a voltage signal that can be further processed.

The CR4120S-25 can be used in a wide variety of applications, including power monitoring, watt-hour metering, energy management systems, battery bank monitoring, and more. It can measure the current in three-phase AC systems, and is also suitable for use in DC variants of these systems. The device is extremely accurate, and its output is linear over its entire measurement range.

The CR4120S-25 also has a wide operating temperature range of -25 to +55 degrees Celsius. This makes it suitable for use in a variety of environmental conditions. It also has a built-in thermal protection system to ensure reliable operation. The CR4120S-25 has a built-in self-test function which confirms the accuracy of its measurements.

The working principle of the CR4120S-25 is straightforward. The current passes through the conductors in the precision measuring cable. The current transformer then amplifies the signal. The output amplifier then converts this to a voltage signal which can be further processed. The device is highly accurate and has a wide range of applications.

Overall, the CR4120S-25 is a reliable and accurate current transducer that can be used in a wide variety of applications. It has an operating temperature range of -25 to +55 degrees Celsius, making it suitable for use in a variety of environmental conditions. The device is also highly accurate and has a wide range of applications. It is a reliable and accurate device that can be used in power monitoring, watt-hour metering, energy management systems, and more.
