High Current Closed Loop Hall Effect Current Sensor High Accuracy
TBC-ECH 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 really
measuring resolution 1000:1 and it uses for precision measurement
of DC, AC and pulse current.

Remarks:
1. All dimensions are in mm.
2. General tolerance ±1.0mm
| Directions for use |
Is 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.
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.
