MV-2520 is a high power, high frequency current transducer designed to measure DC, AC, and pulsed currents from 5 mA to 1000A with a max current rating of 200A. It has a built-in temperature compensation to enable accurate current sensing over a broad temperature range. This current transducer is a widely used instrument in various settings such as scientific research, voltage regulation, current testing, and productivity monitoring.

Application

MV-2520 is primarily used for industrial motor control, electrical system monitoring and protection, energy saving, and renewable energy harvesting. It also finds its application in automotive, solar, mechanical, and hydraulic systems. This current transducer is also employed in many motor control and protection systems in different power sectors. For instance, it is widely used in electrical installations, installations related to electrical control, and ac/dc inverters.

In addition, it is deployed in different fields as a high precision metering device, including temperature, power, pressure, flow, air conditioning, and monitoring/measuring like auto-positioning, robots, and elevator motors. Due to its high power rating and wide current range, it is also applicable in on-board power supplies and airborne applications. Furthermore, the MV-2520 is often used in consumer electronics such as LED systems, TVs, washing machines, and refrigerators.

Working Principle

The MV-2520 current transducer operates on the Faraday’s law of induction. This law states that a current-carrying conductor generates a magnetic field which can be used to control the current flowing through the conductor. The MV-2520 is constructed with a core of ferromagnetic material which is wound with an insulated wire. This core can be magnetized and demagnetized with each current pulse passing through its winding. When an alternating current is applied to the winding, the core magnetizes and demagnetizes with each current cycle, thus producing a varying magnetic field.

When the alternating current is fed through the winding, the core will be alternately magnetized and demagnetized. In turn, this creates a secondary voltage in the winding that is proportional to the alternating current. This induced voltage is then buffered through the output buffer amplifiers in the MV-2520. This amplified output is then converted to a proportional current that is applicable to the power supply and connected load.

Conclusion

The MV-2520 current transducer provides a reliable and accurate means of measuring currents in various types of machines. With a broad measurement range and temperature compensation capabilities, this current transducer is ideal for industrial motor control, electrical system monitoring and protection, energy saving, and renewable energy harvesting applications. Its working principle is based on Faraday\'s law of induction, making it a simple and efficient tool for measuring current in a variety of settings.
