Split Core Current Transformer Hall Effect Based Current Sensor PCB
Mounting
The TBC- Eseries 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. It
provides accurate electronic measurement of DC, AC or pulsed
currents.

Remarks:
1. All dimensions are in mm.
2. General tolerance ±1mm.
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
voltage are available.
