The SCD20PSR is a current transducer with a wide application field. It is a precision current transducer with outstanding accuracy and stability with a greatly improved temperature compensation technique. This transducer is specifically designed to be used for a wide range of applications, from utility substations to industrial power systems. An SCD20PSR is an innovative current transducer developed by Schneider Electric, which employs a brand new technology of sensor-less current measurement. It consists of two core components: a one-piece split-core frame and a high-precision hall-effect-based sensing element. The split-core frame is designed to fit around the conductor, allowing for quick and simple installation with minimal disruption. The sensing element measures current by outputting an analog voltage that is proportional to the sensed current.

The SCD20PSR offers a wide operating range, from 0.01 to 10,000 amps, ensuring it can handle most applications. The accuracy is outstanding, with an error rate of ±0.025 % with the 7-amp input of a current pulse and ±0.05 % with the 20-amp current. Furthermore, the sensing element also has excellent linearity, from 0.0067 % of full-scale measurement. Additionally, the sensing element is temperature-compensated from 10 to 50 °C, guaranteeing stable performance under any temperature conditions.

The working principle of the SCD20PSR is based on a Hall-Effect-Based sensing element. This sensoring element uses a sensitive magnetic field detector, called a Hall sensor. The sensor will measure the strength of the flux produced by the current passing through the conductor, and will output a voltage that is proportional to the detected current. This voltage can then be used to measure the current. The transducer also has a built-in signal conditioner that filters and amplifies the sensed voltage, and converts the analog signal to a digital one for easy monitoring.

The SCD20PSR has a host of features that make it the ideal choice for current transducer applications. It is easy to install and offers accurate measurements in a wide temperature range. The built-in signal conditioner also ensures that any signals detected by the transducer are correctly amplified and converted for accurate measurements. Furthermore, the sensing element is temperature compensated, ensuring that the readings are accurate regardless of the temperatures. The SCD20PSR is the perfect choice for a wide range of current transducer applications.
