CR5211-5

CR5211-5 is a current transducer that benefits from a galvanic isolation element and it provides a reliable and safe way of performance. It allows a high precision conversion of the current signal from the traditional component like panels and resistors. The transducer is capable of registering low-power to high-powered signals over a polarized surface and can measure currents up to 5A.

The application fields of CR5211-5 are quite vast: from the automotive sector to the building applications, the current transducer has already found its place in many places. It is often used in industrial processes for control and measurement of current values. The most common application is seen in the lighting circuits, where it can register and help to control the lighting by – for example – dimming. It is also used in a wide variety of installations, ranging from IT systems, metering devices, security systems and electrical power plants.

The working principle of the current transducer is based on galvanic isolation which is achieved using a combination of resistive and capacitive elements. The device works by sampling the current signal from a voltage source and then isolating the signal from the source. The isolation is achieved by using a linear high impedance input stage and a low impedance output stage. The weakness of the linear input is compensated by using a capacitive feedback loop which is essentially used as an isolation element. The output stage then works by converting the current signal into a voltage signal that can be read by an external device.

This way, the CR5211-5 current transducer provides a conversion system of a wide range of current signals, from low power up to 5A and it is widely used in many applications, from automotive applications to industrial ones: it allows an easy and accurate measurement and control of different current sources.
