50A to 100A input Closed Loop Hall Effect Current Sensor SJ
20790-2000
The TBC-LAH current sensor is a closed loop device based on the
principle of the hall effect and null balance method. The output
from the current sensor is the balancing current which is a perfect
image of the primary current reduced by the number of secondary
turns at any time. This current can be expressed as a voltage by
passing it through a resister. It provides accurate electronic
measurement of DC,AC or pulsed currents.

| Directions for use | 
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 available.
