100a Current Sensor Closed Loop Hall Effect Current Sensor For UPS
SMPS
The TBC- LP 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. It
provides accurate electronic measurement of DC, AC or pulsed
currents.

| Mechanical dimension(for reference only) |
Remarks:
1. All dimensions are in mm.
2. General tolerance ±1mm.
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.
