Current Transducers

The HAT 400-S is a current transducer designed and supplied by HAT Elektronik GmbH as part of the \'S Series\' current transducer range. The transducer has a wide range of applications spanning from industrial automation to metering and audio production. The model features a universal power supply, high accuracy, and could be combined with logic, programming, or interlocking components.

Applications

The HAT 400-S current transducer can be used for a wide variety of applications which involve measuring current. This includes industrial equipment (such as motor current measurements or power switching operations) as well as monitoring power grids and mains electricity supplies. The device can also be used to build up electrical circuits with extra protection against overcurrents, allowing for shorter wiring lengths.

Manufacturers of audio and related equipment such as amplifiers often rely on current transducers due to their accuracy and compatibility with other electronic components. The HAT 400-S can be used to create feedback circuits within audio equipment, enabling designers to optimize performance characteristics. Other applications include safety systems such as fire alarms and emergency lighting.

Working Principle

The HAT 400-S current transducer works by measuring the current in a circuit and converting this to a voltage output signal. The device consists of a coil wound around a magnetic core which is then connected to a miniature part known as a Hall Effect sensor. As the current flows through the coil, it creates a magnetic field. The miniature Hall Effect sensor then detects this field and converts it into an analog voltage which is output from the device.

The Hall Effect sensor in the current transducer is highly accurate, with a tolerance of ±1.5%. It is also capable of measuring currents from a low of 0.5mA up to a maximum of 150A, making it suitable for use in a variety of applications. The device is also very quick to respond, with a response time of less than one millisecond.

Conclusion

The HAT 400-S current transducer is a versatile and highly accurate device which can be used in a variety of applications including industrial, safety, and audio production. By taking advantage of the Hall Effect sensor and magnetic core design, it is capable of accurately measuring currents from 0.5mA up to 150A. Due to its low cost and compatibility with other electronic components, it is a popular choice for many current measurement applications.
