CR4211S-20

Current Transducers

The current transducer is a device that can measure alternating current (AC) and direct current (DC) on an electrical circuit. It can transform the magnitude and direction of current into other electrical quantities, such as voltage or power. They are essential elements of modern industrial and consumer electronics. The CR4211S-20 is a high-efficiency, three-phase AC current transducer which have been widely used in various applications.

Application Fields

The CR4211S-20 current transducer is a core element in electrical power distribution management and can be used to monitor AC three-phase circuits in industrial and commercial electric power systems.

• Data centers: The CR4211S-20 can be used to monitor AC and DC power usage in data centers with its high-efficiency and long-term stability.
• Industrial facilities: This transducer can be used in industrial environments to monitor electric power consumption as well as to control three-phase AC motors.
• Electric power monitoring systems: This product can be used in smart grid projects such as in electric power monitoring systems for transmission and distribution.

Working Principle

The working principle of the CR4211S-20 is based on the Faraday principle of electromagnetic induction.

The device works by having three coils around a hollow circular core, each coil is connected to one phase of the three-phase AC circuit. The device’s magnetic core guides the magnetic field created by each coil and conducts the field lines to the other two coils. This principle creates an induced electromotive force (EMF) in each coil, and the EMF generated is proportional to the current present in the circuit.

The EMF generated by the CR4211S-20 can then be rectified and filtered to generate an analogue DC signal, which can be used to measure and monitor the power consumption of the three-phase AC circuit.

Conclusion

The CR4211S-20 current transducer is a device with high-efficiency and long-term stability for the measurement and current monitoring of AC three-phase circuits. The device works based on the Faraday principle of electromagnetic induction which transforms an AC (or DC) current into an analogue DC signal that can be used to measure and monitor power consumption in regards to the current in a three-phase AC circuit.
