TDC-EA series DC leakage current sensor is a series of new device developed according to principle of electromagnetic induction. Its low current is stable. It is highly insulating between its primary coil and secondary coil. This sensor is used to measure current of signal system, circuit, and leakage monitoring system, as well as to measure current difference. The TDC-LTA series sensor has rated input current between 10mA and 50mA,meansure range upto 75mA. It has 1% accuracy, very reliable. Available for appearance customization.

Directions for use |
1.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)
2. The output amplitude of the sensor can be adjusted according to users’ requirements.
3. Custom design in the different rated input current and the output voltage are available.
