DC Leakage Current Sensor
A new type of current sensor developed by applying the principle of magnetic modulation. The primary current is compensated by the current generated by the internal oscillator to achieve the balance of the magnetic field. At this time, the secondary voltage can accurately reflect the primary current.
Product Features

Excellent accuracy, good linearity
Wide measuring range and strong overload capacity
Perforated structure, no insertion loss
Scope of Application
The signal system
Line detection
Leakage Monitoring System
Current difference measurement
