ZMCT103C 5A AC Current Transformer Module

ZMCT103C 5A AC Current Transformer Module Specifications:

  • On-board precision micro-current transformer
  • On-board high-precision op-amp circuit, to do accurate sampling and appropriate compensation and other functions to signal
  • The module can measure AC within 5A, corresponding output analog can be adjusted
  • Under ideal conditions, the input voltage VCC is 3-35V, according to the potentiometer (adjust the amplification ratio, amplification range 0-100 times) to adjust the required output voltage, but the output (OUT) of the maximum voltage does not exceed 1 / 2 VCC.
  • The output signal is the AC voltage signal, and the output signal voltage does not exceed the maximum 1 / 2VCC.
  • PCB board size: 38 (mm) x 18.5 (mm)



ZMCT103C 5A AC Current Transformer Module used for measurement of alternating electric currents. When the current in a circuit is too high to apply directly to measuring instruments,

a current transformer produces a reduced current accurately proportional to the current in the circuit

which can be conveniently connected to measuring and recording instruments. A current transformer isolates the measuring instruments from what may be very high voltage in the monitored circuit.
