LD1 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.

Remarks:
Directions for use:
1. When the current to be measured goes through the sensor, it will be output at the terminal. (Note: Incorrect wiring may result in sensor damage).
2. Custom design for different rated input and output currents is available.
