Current transducers are electrical devices used to measure the flow and intensity of electric current. The HAS 400-S transducer is a high accuracy, microprocessor-based current transducer from Advanced Measurement Technology. It has a wide range of applications in instrumentation, power electronics, research, and industrial process control, as well as in other current sensing applications.

The HAS 400-S is an integrated current measuring unit consisting of a single-element current transformer, an AC voltage source, and an operational amplifier. The single-element current transformer is composed of a primary coil that senses the current, a secondary coil that is connected to the AC voltage source, and an operational amplifier that amplifies the voltage signal from the secondary coil. The output of the operational amplifier is then converted to a digital signal. This digital signal can be used for various purposes, such as measuring the current, controlling the current flow, monitoring the current, and detecting faults.

The operation of the HAS 400-S is based on the principle of the Hall effect. When a current is passed through the primary coil, a voltage is induced in the secondary coil. This voltage is proportional to the current and is measured by the operational amplifier. The output of the amplifier is then converted into a digital signal, which can be used to measure the current. The measurement accuracy of the HAS 400-S is 0.22%.

The HAS 400-S is designed for use in industrial and laboratory settings. It can be used to measure both AC and DC currents and has a wide dynamic range, from 0.05 to 200 Amperes. The signal from the HAS 400-S is customizable: it can be provided in either voltage or current form, and can be scaled according to the application. The device is also equipped with a zero-sensing feature, which eliminates the need for manual zeroing.

The HAS 400-S is easy to install and use, and can be used for applications such as motor and transformer overload protection, induction and synchronous motor control, power supply regulation, and AC voltage measurement and control. It is also highly reliable and stable, and can withstand temperature fluctuations, noise, and vibration. The device has a built-in self-test feature that allows for easy troubleshooting and maintenance.

The HAS 400-S is a highly accurate and reliable current transducer, suitable for a wide range of applications. It has a wide dynamic range, is easy to use and maintain, and is available in both analog and digital forms. Because of its high performance, the HAS 400-S is suitable for a variety of current sensing applications in both industrial and laboratory settings.
