CR4220S-30

Current transducers are specialized sensing devices designed to detect, measure, or convert a variable current value into a proportional electrical signal. They have a wide range of applications in industrial, commercial, and residential environments. One example of a current transducer is the CR4220S-30, which measures AC current and provides a perfectly precise, smooth, and stable output signal proportional to the input current.

The CR4220S-30 is a single-channel current transducer characterized by low temperature drift, low error, and high accuracy. It uses advanced power line coupled communications technology and is designed for use in residential, commercial, and industrial applications. The transducer has a signal rejection ratio of 10:1, an amplitude of 450V Maximum and 10V Output, and a frequency of 400 Hz - 70 kHz.

The main application fields of the CR4220S-30 include power measurement, power control, motor control, and inverters. Additionally, the transducer is suitable for use in industrial equipment, such as welding machines and automated production equipment, that rely on measuring and controlling current. The CR4220S-30 is also capable of measuring frequencies up to 70 kHz, making it suitable for use in other high-frequency applications.

The CR4220S-30 works by converting the AC current input to a DC output. The transducer translates the input current into a variable voltage which is then converted into an output signal. This signal is proportional to the current input and is used to measure and control the AC current. The transducer utilizes an analog-to-digital conversion process that allows it to have a fast response time and higher accuracy.

The CR4230S-30 is equipped with an isolation feature that helps protect the transducer from high voltage spikes and transients. Additionally, the transducer has an over-voltage protection system that can protect the transducer from voltage shocks up to 600V. The transducer also uses a varistor to protect it from over-currents and has a current-meter selection switch.

The CR4220S-30 is a reliable and accurate current transducer designed for use in a variety of applications. It is capable of converting AC current into a stable and proportional electrical signal, allowing it to measure, control, and detect a variety of currents. The transducer has a high-frequency response and advanced power line coupled communications for precise and accurate measurements. Additionally, the transducer is equipped with several protective features to protect the transducer from electrical shocks and transients.
