WCS2801 Bidirectional AC/DC current detection module
0-1A input -----0-4V output
Real-time detection of AC OR DC current range

1. Working voltage: 9-12v;

2. Input current signal range: 0-1A,Aout analog signal output 0-4v;

3. The analog output signal can be flexibly amplified: it can be achieved by multiplying the amplifier resistance

4. Accuracy within 1% of high precision grade;

Principle description:

The module can realize current sampling, the sampling the analog signal to the corresponding proportion of amplification processing,
formula to produce Aout=4*ia (ia current through the wire）
Physical module:

Figer1

module size figure 2 

Dc current:

formula:Aout=4*ia

Forexampleif the current ia=1A ,Vout=4V;

AC test section:

The sinusoidal analog signal is used as a full wave rectifier. The following is the measured data section

  Yellow is the input waveform and blue is the full waveform after the full wave rectifie
