    400A-20000A Hall Effect Current Sensor Details

    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.

    Is your Hall effect current sensor output bidirectional?
    For your ATO-CUS-ACDC20000 current sensor, it says the sensor output is 0-5VDC. Wish to confirm that output is bi-directional?
    From: Hensley | Date: 28/11/2021
    Was this review helpful? Yes No (0/0)
    ATO Responded
    Yes, the output is bi-directional, it is 0 ~±5V.
    Output is 0 to +5VDC in one direction of current flow and 0 to -5VDC in the opposite direction of current flow.
    Our requirements for current sensor
    We are looking to order a suitable  /-15 V DC power supply. What is the current draw of the ATO-CUS-ACDC20000? Also, are there any requirements around a minimum voltage ripple from the supply? Please let me know any special requirements that the power supply may need to ensure compatibility with the ATO-CUS-ACDC20000.

    Was this review helpful? Yes No (0/0)
    ATO Responded
    1. The current consumption of ATO-CUS-ACDC20000 is 0.5W, and the output voltage ripple V1V2≤ 150mV.
    2. We recommend ATO-SMPS-D20, input voltage AC180-264VAC, 50/60Hz, output V1: +15V (0.8A), V2: -15V (0.2A), price is 62.5USD/ PCS, free shipping.
    Please see the attachment.
    Can you tell me some parameters of the Hall current sensor?
    Could you tell me the impedance of the ATO-CUS-ACDC20000 sensor? The output signal is 5VDC for AC and DC?
    From: Zma | Date: 06/09/2021
    Was this review helpful? Yes No (0/0)
    ATO Responded
    The impedance of the ATO-CUS-ACDC20000 sensor is approx 250Ω, power consumption ≤0.5W, and the output signal is 5VDC for AC and DC.
    Range of current sensor
    For your current sensor of 2000A range, how much over range is permitted before clipping. We are hoping for 2400A (120% )?
    From: Wulph | Date: 05/07/2021
    Was this review helpful? Yes No (0/0)
    ATO Responded
    Yes, up to 2400A is okay.
