01, on-board precision miniature voltage transformer 02, on-board high-precision op amp circuit, the signal to do accurate sampling and appropriate compensation function 03, the module can measure less than 250V AC voltage, corresponding toExportAnalog can be adjusted 04, PCB board size: 49.5 (mm) x19.4 (mm)
AC85 - 264V or DC110 - 370V wide voltage input DC3.3V(+/ -1%) 1A isolated output Input Current: 0.5mA/115VAC 0.25mA/230VAC Input surge current: 10A (230VAC) Frequency range: 47-63Hz Operating Temperature: -30 - 70 ? Relative humidity: 20%- 90% Rated power: 3.5W Output efficiency: 61% Module size: 5.1*2.3*1.8cm
Input and output voltage can display alternately The starting state can be set freely. This modlue has the function of controling the start-up and shutdown by the button. So it can control easily the state of output This module have the big power MOS to protect the circuite in case of connecting reversely. This can improve the effiency and reliablity.
