Description

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.
