CR4480-0.5

Current transducers are devices that provide reliable measurements of AC, DC, variable, and pulse currents over a range of scales. A common example of a current transducer is the CR4480-0.5 series, which is used to convert a measured current into an analog input or output signal. The CR4480-0.5 is an ideal tool for voltage regulation, monitoring, and protection applications.

The CR4480-0.5 is a bi-directional current transducer designed to measure alternating current over a broad range of power supplies. The input of the device is the AC source current, and the output is an AC signal proportional to the input current. The device features an open-loop wide-bandwidth low-noise amplifier with a gain of up to 5A/V and a high frequency response of up to 20 kHz, allowing it to accurately measure both AC and DC currents. The device also has an input voltage range of 4 to 25 VDC, and an output impedance of 2 ohms. The output current is adjustable from 0.5 mA to 5A.

The CR4480-0.5 has two operating modes, the first being constant voltage mode. This mode is used when the output load is constant and the input current remains the same. In this mode, the device will keep the output locked at the desired voltage. The second operating mode is variable voltage mode. This mode is used when the output load is dynamic and the input current is changing, such as in a motor drive application. In this mode, the device will adjust the output voltage to keep the output current constant.

The CR4480-0.5 has a number of features that make it suitable for use in a variety of applications. One such feature is its high accuracy, which can be adjusted from 0.1% to 0.5%. It also has a wide operating temperature range, from -40°C to 70°C. The device is protected from short-circuit events, and has a high EMI/RFI immunity. It also has a wide input voltage range of 4 to 25 VDC and a low power consumption.

The CR4480-0.5 is a robust and reliable device that can be used in a variety of AC and DC applications, including motor drives, voltage regulation, energy meters, inverters, solar and wind turbines, home automation, and other industrial and commercial applications. The device is well suited for applications where accurate and reliable current measurement is required.

In conclusion, the CR4480-0.5 is a versatile current transducer with a wide range of features that make it ideal for numerous applications. It is a reliable, accurate, and efficient device that can be used to measure AC or DC currents over a wide range of scales. The device has a wide input voltage range and a high EMI/RFI immunity, ensuring reliable operation.
