Pulsed Current Low Current Hall Effect Sensor For Uninterruptible
Power Supplies
TBC-DHT 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.

Remarks:
1. All dimensions are in mm.
2. General tolerance ±1mm
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 are available.
