Tips: The newest Hall Effect current sensor for AC/DC 400A to 20000A
The stability and accuracy of the output current is critical in high-power and high-frequency switching power supply. Now the detection of output current mainly uses the shunt and Hall Effect current sensor. In the case of high current, the volume of the shunt should be very large to guarantee stability, and there is a problem that it cannot be isolated. In the case of the high-power and high-frequency switching power supply volume become smaller and smaller, the manufacturers generally use Hall Effect current sensor to ensure making smaller volume to achieve physical isolation, safe and reliable. In the high frequency situation, the iron core will heat in the conventional Hall current sensor. This will result in the current sensor output deviation from the actual value or even no signal output and lead to return circuit abnormal in high-frequency switching power supply feedback, thus affecting the high-frequency switching power supply instability or even damage.The new Hall Effect current sensor applies Nano-crystalline as the magnetic core material, the permeability, excitation current and iron loss of the core are superior to the silicon steel core, and the strip thickness is only about 0.03mm. Its resistivity, hardness, tensile strength is also higher than the silicon steel core, which can effectively solve the heating phenomenon for current sensor in the high frequency current. And it greatly improves the hall current sensor reliability and service life. ATO-AHKC-KA is an open loop current sensor. The inner hole is 104*36mm, and the measurement current is up to AC/DC 5000A. In the case of ensuring the same current, the size is smaller, with split-core structure, easy to install. The redesigned circuit structure has optimized high-frequency circuit’s response time and long-term stability.
