The single-phase AC active output voltage mutual sensing module is equipped with ZMPT101B series high-precision voltage transformer and high-precision current operational amplifier, which is easy to collect AC power signals within 250v.

Voltage Transformer: On-board precision miniature voltage transformer.

Operational amplifier circuit: On-board high-precision amplifier circuit, accurate sampling of the signal and appropriate compensation and other functions.

Mode voltage output: the module can measure AC voltage within 250V, and can adjust the corresponding output mode.

Output signal: the output signal is sinusoidal, median waveform (DC component)

Power supply voltage: 5-30V

Adjusting the potentiometer can change the amplitude of the output waveform (the adjustment process does not change the median value)

The range of waveform change is between 0-VCC; if the waveform is distorted during the process of increasing the amplitude, it can be solved by increasing the working voltage VCC appropriately,

If the median value of the waveform is shifted to 0, a capacitor of about 105 pF can be connected in series with the OUT terminal to filter out the DC component in the waveform.
