Key Technology

Based on the principle of magnetic modulation and Fourier transform software algorithm, high-precision and compatible residual current (B-type, composite type, smooth DC, A-type, A-type superposition, and AC type) detection schemes are completed.

Characteristic

• Compact design, single PCB packaging, no need for peripheral hardware circuits and software algorithm processing;
• It has fast response and judgment output functions, can perform self correction, and comes with self checking function;
• Can achieve high-precision detection of small current, large current, and high-frequency (3KHz) AC residual current;
• High performance EMC shielding function and a wide range of operating temperatures (-40~+105 ℃).
