Current Transducers

A current transducer is an electronic device used to convert a signal carrying an electrical charge of current into a proportional analog or digital output signal. It is used to measure the magnitude and direction of electric current in a system, allowing control of electric systems from a distance. The ACS724LLCTR-30AB-T is an example of a current transducer used in signal conditioning and voltage detection applications.The ACS724LLCTR-30AB-T is a low-power Hall-effect current transducer with an analog output. It can be used for measuring current from ±30A up to ±6A with an output of 0.5 to 4.5V. It is a robust device with a high accuracy output (±1%), wide and flat frequency response (20–250 kHz for 0A–30A), low power consumption and low noise characteristics. The ACS724LLCTR-30AB-T has a wide operating temperature range of -40℃ ~ +125℃ and a static linearity of +/- 0.5%.The ACS724LLCTR-30AB-T is most commonly used in switching power supplies, DC-DC converters, inverters and electric vehicle charging systems. It is also used in applications such as building energy management systems, uninterruptible power systems (UPSs), industrial drives, and smart grid and energy storage systems.The working principle of ACS724LLCTR-30AB-T is based on the Hall Effect. It works by detecting the change of magnetic flux produced by the current movement in the conductor that causes a voltage drop across the Hall sensor. The Hall voltage generated is proportional to the current passing through the conductor, and this value is then amplified and converted into a voltage output.The ACS724LLCTR-30AB-T features a low power consumption (4mA maximum, excluding logic supply), a quiescent current of 4mA at 30A, a VREF voltage source of 4.5V @ 2.5mA, an accuracy of 1% and a linearity of 0.5%. Its operating temperature range from -40 ~ +125°C and its static offset voltage (VOS) of 0.2mV@-30~30A make it an ideal choice for low-power applications.The ACS724LLCTR-30AB-T current transducer is a compact device with a wide range of applications and features. It is an excellent choice for applications requiring accuracy, low noise and low power consumption, such as switching power supplies, DC-DC converters, inverters and electric vehicle charging systems.
