Perforated high-precision small current 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.

Measurement Range: 0-15mA (10mA model), 0-75mA (50mA model), 0-300mA (200mA model)
Power Supply: ±12V to ±15V (±5%)
