Current transducers are devices that can measure and convert the current applied to a load into an electrical signal of a known value. The CR4480-15 is a device used to measure current or voltage in the 0-15A range for measurement and control applications. In terms of its applications, this current transducer is suitable for building automation, motor control, power conditioning, power distribution, and motor protection applications. Furthermore, this current transducer can be used in safety-related applications involving hazardous and classified areas.

The working principle of the CR4480-15 is the voltage-drop and the wattmeter principle. The voltage-drop principle is based on the concept that when a current flows through a single electric conductor, its voltage drop is proportional to its resistance. The wattmeter principle works on the same principle, but also takes into account the power that the current generates. In order to measure the current or voltage being applied to a load, the CR4480-15 measures the voltage drop and wattage across the load. The impedance of the load is then measured, and the measured voltage drop and wattage are used to calculate the current or voltage that is being applied to the load.

The CR4480-15 transducer provides accurate and reliable measurements of current or voltage in the 0-15A range. The design has low-end sensitivity of 5mA and a maximum overload capability of 5 times full scale for AC and 10 times full scale for DC. Other features of this transducer include a wide operating temperature range of -40°C to 80°C, an optional display for easy operation, and short-circuit protection. The device has protection against dust, water, and corrosion, making it durable and reliable.

Aside from its measurement and control applications, the CR4480-15 transducer can also be used in battery and charging systems. It can measure the voltage and current of a battery and determine its charging rate and duration. It can also be used to regulate the voltage and current in order to protect the battery from overcharging and undercharging. Additionally, the transducer can be used to measure the efficiency of a charging system, allowing engineers to optimize and improve the charging process.

In conclusion, the CR4480-15 current transducer is a reliable and accurate device for measuring current or voltage in the 0-15A range. Its working principle is based on the voltage-drop and wattmeter principles, which allow it to accurately measure the current or voltage being applied to a load. Furthermore, the device is suitable for a wide range of applications, including motor control, power distribution, and safety-related applications, as well as battery and charging systems. With its wide operating temperature range and protection against dust and corrosion, the device is sure to provide reliable and accurate measurements in any application.
