Hall Effect Current Sensor Directions for use
- When measure current flows according to the direction of the arrowhead, Output terminal gets the same phase current.
- The primary conductor should be≤120℃.
- The dynamic performance (di/dt and the response time) is the best when the primary hole is fully filled with
- the bus bar.
- The primary turns should be at the top of the sensor for the best magnetic coupling.
- 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)
- Custom design in the different rated input current and the output current are available.
