Description
The ACS37030 Current Sensor is an advanced current sensor module that combines the Hall effect and an inductive coil, allowing measurement of both the DC and AC components of the current signal. This provides an exceptionally wide bandwidth of up to 5 MHz for DC signals, enabling precise real-time monitoring of dynamic current variations. One of the key features of this module is its ultra-fast response time of just 40 ns. This makes the sensor an ideal solution for applications requiring ultra-fast current change detection, such as motor control systems, power converters, protection circuits, and energy monitoring systems. The sensor provides galvanic isolation between the current path and the measurement circuits, ensuring safety and minimizing interference. Its conductive path features a low resistance of just 0.7 mΩ, reducing power losses and enabling efficient operation in high-current systems. Additionally, the PCB is made of high-quality copper, further improving its electrical properties.
The sensor output is non-ratiometric, meaning that its zero point and sensitivity are independent of the actual supply voltage, eliminating the influence of power line noise. The sensor's output signal is an analog voltage proportional to the measured current. With a built-in VREF reference output, the sensor enables pseudo-differential signal transmission, significantly improving noise immunity in challenging application environments. Additionally, the built-in digital temperature compensation ensures high measurement accuracy over a wide temperature range.
The module is designed for easy integration into various systems. It offers multiple mounting options, including standard 2.54 mm pins, screw terminals, and mounting holes, allowing for quick and convenient connection to the circuit. Pin labels are printed on the PCB to facilitate correct wiring.
The ACS37030 sensor is suitable for a wide range of applications, including energy management systems, battery monitoring, electric motor speed control, short-circuit detection, power converters, and protection systems. Thanks to its advanced parameters and flexible mounting options, this sensor is an excellent solution for professional projects requiring high-speed and high-accuracy current measurement.
