CR5210-2 current transducers are designed to accurately measure and convert currents up to 2,000 amps. These transducers utilize a low-cost, three-phase, closed-loop current transformer and a high-precision open-loop current three-phase sensor for current measurement. In addition, the CR5210-2 incorporates a built-in current regulator, which provides constant output current, regardless of the load on the input current. This ensures that the accuracy of the current measurement is maintained even when the input current is varying significantly.

In addition to current measurement, the CR5210-2 is also designed to be used as a current monitoring device. The current sensed by the device can be used to detect any fault conditions, short-circuit current and overloads. In addition, the CR5210-2 can be used to detect any change in the current character, including high-frequency current fluctuations. The CR5210-2 is also suitable for measuring of short-circuit currents. It can detect any short-circuit current up to 10 times of the normal running current, which makes it ideal for fault detection applications.

Working Principle:

The CR5210-2 is a passive current transducer and works on the principle of magnetic induction. The primary winding of the transducer is connected to the three-phase supply and the secondary winding is connected to the load. The three-phase current in the primary winding is converted to a DC signal by means of a bridge rectifier. This DC signal is then applied to the open-loop current three-phase sensor. The analog output of the sensor is then converted to a current code signal, which is further processed by the built-in current regulator. The current code is then sent to the central processing unit (CPU), which converts it to the desired current output.

Features:

The CR5210-2 provides highly accurate current measurements with excellent dynamic accuracy. It is a low-cost, three-phase, open-loop current transducer. It can detect any change in the current character, including high-frequency current fluctuations. The built-in current regulator ensures consistent current sensing, regardless of the load on the input current. In addition, the CR5210-2 has a wide range of operating temperature, from -25°C to +85°C. It is designed to operate in harsh industrial environments, including wet and dry conditions.

Applications:

The CR5210-2 is ideal for current measurement and monitoring applications in power plants, industrial facilities, and commercial buildings. It is particularly suitable for measuring short-circuit currents and detecting any fault conditions, overloads, or high-frequency current fluctuations. It can also be used for power factor correction, load balancing, current balancing, and other power related applications.

Conclusion:

The CR5210-2 current transducer is a low-cost, three-phase, open-loop current transducer designed to monitor and measure currents up to 2,000 amps. It provides highly accurate current measurements with excellent dynamic accuracy. The built-in current regulator ensures consistent current sensing, regardless of the load on the input current. In addition, the CR5210-2 has wide range of operating temperature, making it suitable for harsh industrial environments.
