WBI224LY05-25 (Split Core Hall Effect Current Sensor) adopts the Hall Effect to measure AC and DC current in the power grid in real time. Using precision constant current technology and linear temperature compensation technology, the Split Core Hall Effect Current Sensor converts the measured current into a standard current output, featuring AC/DC general-purpose capability, strong overload capacity, and high isolation.

Installation and Usage Instructions
(If the product uses wire output and the wire colors differ, refer to the actual product for the final color coding.)
1. Pin definition:
Auxiliary power positive (red)
Auxiliary power negative (white; not used for single power supply)
GND: Auxiliary power ground (black)
OUT: Output (brown)
2. A forward voltage output is obtained when the input current flows in the direction of the arrow.
3. When the measured current is less than half of the rated value, higher accuracy can be achieved by using multiple windings:
(Measured Current Value × Number of Turns = Rated Input Ampere-turns).
Applications:
Current measurement
Automatic monitoring and control
Electrical signal detection and modulation
Data acquisition
