    Note: ATO can customize DC bidirectional current sensor with maximum measuring range of -50A~0~50A. For example, the measuring range of input current is -50A ~ 0 ~ +50A, and the output signal is 4-20mA. Then the output signal 4-12mA corresponds to -50A~0, and the output signal 12-20mA corresponds to 0~+50A. And so on for other output signal modes.

    FAQ
     ❯

    Yes. In applications where electrical isolation, safer installation, and analog signal output are desired, this sensor is an excellent substitute for traditional shunt-based current sensing.

     ❯

    While designed for good immunity, interference from VFDs or strong magnetic fields may still affect performance. Recommended practices include:

    • Shielded cabling
    • Distance from high-frequency devices
    • Using metal enclosures or closed-loop (feedback) models for enhanced EMI resistance
     ❯

    Yes. When used together with a voltage signal and phase angle (if AC), you can calculate: Power (P) = Voltage (V) × Current (I) × Power Factor (cosφ) This is useful in power monitoring, energy management systems, smart meters, and industrial automation.

    solid current sensor with 4-20ma output
    Picked up this current sensor for a power monitoring panel. The wiring was pretty straightforward, and the 4-20mA output made it easy to connect to my controller. I checked the reading against my meter a few times and it was close enough for what I’m doing. The housing also feels pretty solid.
