1. All dimensions are in mm.
2. General tolerance ±1mm.
3. Elucidation:  1:+15V  2:-15V  3:I0UT
Directions for use
1. When measure current flows according to the direction of the arrowhead, Output terminal gets the same phase current.
2. The primary conductor should be≤120ºC.
3. The dynamic performance (di/dt and the response time) is the best when the primary hole is fully filled with the bus bar.
4. The primary turns should be at the top of the sensor for the best magnetic coupling.
5. When the current will be measured goes through a sensor, the voltage will be measured at the output end.(Note: The false wiring may result in the damage of the sensor)
6. Custom design in the different rated input current and the output current are available.
