Description
Description
Introduce

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.

Applications
Variable speed drives
Welding machine
Battery supplied applications
Uninterruptible Power Supplies (UPS)
Electrochemical
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 current are available.
