ZMPT101B 2mA Active Single Phase Voltage Sensor Transformer Module AC Output Voltage Sensor for Arduino

Product description:   Single-phase AC active output voltage mutual inductance module equipped with ZMPT101B series of high-precision voltage transformer and high-precision op amp current, easy to 250v within the AC power signal acquisition.   Product parameters:

• Voltage Transformer: Onboard Precision Micro Voltage Transformer
• Operational amplifier circuit: high-precision on-board amplifier circuit, the signal to do the exact sampling and appropriate compensation and other functions
• Mode voltage output: the module can measure AC voltage within 250V, the corresponding output mode can be adjusted
• Output signal: the output signal for the sine wave, the waveform of the median (DC component)
• Supply voltage: 5-30v

  Product manual:  

• Adjust the potentiometer can change the amplitude of the output waveform (the adjustment process does not change the middle value)
• The waveform changes in the range of 0-VCC between; in the process of increasing the amplitude if the waveform distortion, can be appropriately increased by working voltage VCC to solve,
• If the median value of the waveform is shifted to 0, a capacitor of about 105 pF can be connected in series at the OUT terminal to filter the DC component in the waveform.
