6pcs 5-30V ZMPT101B Voltage Transformer Module, Single Phase Active Output AC Voltage Sensor Board Power Supply Voltage for Household Appliances

Product description Instructions:1. When L, N is connected to AC220V. VCC, GND input DC5V-30V. OUT, GND connected to the oscilloscope can get a sine wave.2. Adjust the potentiometer can change the amplitude of the output waveform (the middle value will not change during the adjustment process), the waveform of the range of 0-VCC;3. If the waveform is distorted in the process of increasing the amplitude, it can be solved by appropriately increasing the operating voltage VCC. If you want the middle value of the waveform to move to 0 o'clock, you can connect a capacitor of about 105pF in series with OUT to filter out the DC component in the waveform.Package Includes:6 x Voltage Transformer Module
