●HIGH ACCURACY CONFIGURE: Equipped with ZMPT101B series high accuracy voltage transformer and high accuracy operational amplifier circuit, which can easily realize 250V AC power acquisition
●SIZE: Approx. 50 x 20mm / 1.97 x 0.79in
●ACCURATE SAMPLE & PROPER COMPENSATE: Equipped with accurate miniature voltage transformer, the module has the ability to accurately sample and properly compensate the
●MEASURE WITHIN 250V AC VOLTAGE: The module can measure AC voltage within 250V, which can be adjusted according to the output analog quantity


Description

How to Use:
1. When L and N are connected to AC220V, VCC, GND input DC5V?30V. Connect OUT and GND to an oscilloscope to get a sine .
2. Adjusting the potentiometer can change the amplitude of the output waveform (the middle value will not change during the adjustment process), and the waveform in the 0?VCC range.
3. If waveform distortion occurs in the process of increasing the amplitude, can be solved by appropriately increasing the working voltage VCC. If you want to move the middle value of the waveform to 0 oclock, you can connect a capacitor of about 105pF in series with OUT to filter out the DC component in the waveform.
