Current transformers (CTs) are an important part of modern electrical systems, converting high voltage and/or high current inputs, to a lower voltage and/or lower current outputs. They are widely used in electrical networks to measure currents, protect against overloads and regulate voltage. The CR5210S-75 is a high-accuracy, low-cost current transformer designed for use in multiple application fields.

The CR5210S-75 current transformer is based on a toroidal core, comprising two symmetrically-shaped but independently-connectable windings. This type of transformer is capable of accurately measuring AC current in a wide range of frequencies, to a very high degree of precision. The core used in the CR5210S-75 contains a low-loss composite material, ensuring an accurate output across a wide frequency range.

The CR5210S-75 is designed for use in multiple application fields, ranging from impulse voltage measurements, to logging in renewable energy power systems. It is also suitable for applications such as LED lighting systems, or for measuring electricity use in residential or industrial establishments. The CR5210S-75 has a rated operational temperature range of -40°C~120°C, making it suitable for use in extreme weather conditions.

The CR5210S-75 measures in both directions, measuring both positive and negative currents, and can be used in both DC and AC applications. It also offers good accuracy and stability over time, with a typical accuracy of 0.2% up to 10mV. This makes it suitable for accurate measurements of electrical parameters such as power and energy.

The working principle of the CR5210S-75 is based on Faraday\'s law of induction. When a current passes through the primary transformer winding, it induces a magnetic field in the transformer core. This magnetic field is then picked up by the secondary winding, which produces a lower voltage and/or lower current output. This output is then sent to the measuring equipment for further processing. The CR5210S-75 is designed to provide a reliable signal output, and has a low-noise signal level of 2.5mV/A.

The CR5210S-75 current transformer is designed for a wide range of applications, thanks to its high accuracy, stability, and low-cost design. It is suitable for applications such as impulse voltage measurements, energy management, power logging in renewable energy systems, and more. It offers an accurate output across a wide frequency range, and is capable of measuring both positive and negative currents. It also has a low-noise signal level, making it suitable for low-noise environments.
