Mechanical Dimensions: All dimensions are in mm with a general tolerance of ±1mm.

Directions for Use:

Current flows in the forward direction as indicated by the arrowhead.
The primary conductor should not exceed 120°C.
Optimal dynamic performance is achieved when the primary hole is fully filled with the bus bar.
Voltage is measured at the output end when current passes through the sensor.
Customizable output amplitude and design for different rated input currents and output voltages are available.

Characteristics Charts: Includes pulse current signal response characteristics and effects of impulse noise, as well as input current-output voltage characteristics.
