100a Current Sensor Closed Loop Hall Effect Current Sensor For UPS SMPS
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.
| Directions for use |
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.
