WBI222LY05-25 (Split Core AC Current Transducer) adopts the Hall effect to measure AC and DC current in the power grid in real time. By using precision constant current technology and linear temperature compensation technology, it converts the measured current into a standard current output signal. It features AC/DC current general-purpose capability, strong overload capacity, and high isolation.

Supplementary Notes
Performance Trade-off: The I221LY05-25 features the fastest response time (50us) but supports AC/DC dual-mode input; the I222LY05-25 and I224LY05-25 offer DC-only input with slower response but broader power supply compatibility for the former.
Application Scenarios:
I221LY05-25: Suitable for mixed AC/DC signal detection (e.g., industrial power monitoring).
I222LY05-25: Ideal for stable DC signal transmission with flexible power options.
I224LY05-25: Meets industrial standard 4-20mA signal output for long-distance transmission.
