Multi Range Closed Loop Hall Effect Current Sensor Hall Effect High
Current Sensor
TBC-A05 multi-range current sensor is a close 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.

Directions for use
When the current will be measured goes through a sensor ,the
current 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.
