Pulsed Current Low Current Hall Effect Sensor For Uninterruptible Power Supplies
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.

| 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 are available.
