About this item

  • Analog voltage output：The module can measure AC voltage within 250V and the corresponding analog output can be adjusted.
  • Output signal：The output signal is a sine wave, and the median value of the waveform (DC component) is 1/2 VCC.
  • With ZMPT101B series: 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
  • Operational amplifier circuit: high-precision on-board amplifier circuit, the signal to do the exact sampling and appropriate compensation and other functions
  • Voltage Transformer: Onboard precision micro voltage transformer. Supply voltage: 5-30v


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:
4 x Voltage Transformer Module
1 x Dupont Line

I made a few of them work by desoldering the transformer off the board. Something wrong with the opamp provided

I will measure 5 amps AC at 60hz with a 100 ohm resistor across the output.At 60hz it saturates at 1.5 amps without an external load.With 100 ohm load it puts our 100mv ac for 1 amp input.
