The TBC-EH Series current sensor is a closed loop device based on the measuring principle of the hall effect and null balance method, with a galvanic isolation between primary and secondary circuit, the size of primary not affect test precision, no matter the location of primary in the hole of current sensor. It can really measure resolution 1000:1 and it uses for precision measurement of DC, AC and pulse current.

M echanical dimension(for reference only)
1. All dimensions are in mm.
2. General tolerance ±1.0mm
Directions for use
1.Is will be in a forward direction when the Ip flows according to the direction of the arrowhead.
2.The primary conductor should be≤120℃.
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 voltage are available.
