Directions for use
It will be in a forward direction when the Ip flows according to the direction of the arrowhead.
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.
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)
Customs can adjust Output amplitude of the sensor by needs.
Custom design in the different rated input current and the output voltage are available.
