Current transducers are electrical devices used to measure current in electrical circuits. They help ensure a safe and reliable electrical system by providing high accuracy and resolution current measurements. The DHR 300 C240 is a type of current transducer used for energy metering and protective applications. It is a high-end transducer with a wide dynamic range and low power consumption.

The DHR 300 C240 is based on a Rogowski coil principle. It consists of a highly tuned Rogowski coil assembly and a signal conditioner integrated into a compact package. The Rogowski coil is a precision wound, low-resistance high-inertia coil. It is designed to sense the current flux around the conductor being monitored. The signal is then amplified in the signal conditioner and made available as either an analog current or voltage output. The signal conditioner also has a built-in current-limiting circuit to protect the Rogowski coil from possible overload or short-circuit conditions.

The DHR 300 C240 is designed for a wide range of industrial applications where precise current measurements are required. It is well-suited for use in power and distribution systems, process controls, grounding systems, motor control centers, and smart grids. It can be used in continuous monitoring, energy metering, reactive power compensation, and power monitoring applications. The transducer is also designed for safety and reliability, with short-circuit rated current and over-current protection.

The wide dynamic range and high accuracy of the DHR 300 C240 make it well-suited for measurement of alternating and direct current, as well as single- and three-phase current. It has a selectable output of 0 to 10A, 0 to 16A, or 0 to 32A full-scale output current. The frequency range is from DC up to 400Hz, with a response time of less than 1 millisecond. The output voltage has a tolerance of up to 5%, while the linearity is up to 0.5% maximum. The device is also temperature compensated over the range of -15 to +50°C.

In addition to its accurate and reliable current measurement capabilities, the DHR 300 C240 also features built-in lightning protection and electromagnetic interference screening for added safety. The device is designed for use in harsh and demanding environments, with an operating temperature range of -25 to +50°C and an IP65 rating for protection against dust and moisture. It is also tested to IEC62109-1 and IEC62109-2 standards for safety and reliability.

The DHR 300 C240 is a high-end current transducer, with a wide dynamic range, low power consumption, and high accuracy and resolution current measurement. It is well-suited for use in industrial applications, power distribution systems, process control, ground systems, motor control centers, and smart grids. The robust construction and built-in protection and screening features make it suitable for use in harsh and demanding environments. It can be used for energy metering, protective applications, and other continuous monitoring and power monitoring applications.
