Description:

High Precision ZMCT103C 5A AC Current Sensor Module ESP32 - Single Phase, Active Output, Micro Current Transformer

The ZMCT103C is a high-precision microcurrent transformer sensor module designed to measure AC current up to 5 Amps. This sensor module is based on the ZMCT103C IC and provides an analog output corresponding to the AC current passing through the wire.

Color Variations: Please note that the ZMCT103C Current Sensor may come in two different colors depending on the batch. When you place an order, you will receive one of the available colors at random. Rest assured, the performance and specifications remain consistent across all color variations.

Features:

Current Ratio: 5 A:5 mA
Rated Primary Current at 50/60 Hz: 5 A
Maximum Primary Current at 50/60 Hz: 20 A
Transformer Turns Ratio: Np:Ns = 1000:1
Isolation Voltage: 4500V
Winding D.C. Resistance at 20 °C: 155 Ω
Operating Temperature: -40 to 85 °C
Pin Length of the Secondary Coil (Encapsulation): > 3mm
Epoxy Encapsulation
Pin Configuration:

Pin 1 & 2: Ground (G)
Pin 3: Analog Signal Out
Pin 4: VCC (+5V)
Applications:

HEV inverters
Electronic power steering systems
Overload detection circuits
Industrial and consumer inverters
Tripping and underload circuits
Working Principle: The ZMCT103C operates on the principle of magnetic field variation between two coils. It generates highly accurate, low-noise output voltage signals proportional to the applied AC current. The sensor module is donut-shaped with an epoxy encapsulation, inside which a secondary coil (Ns) is coiled around a ferrite bead. The wire whose current is to be measured is passed through the donut hole, acting as a primary coil, and the change in the magnetic field results in the desired outputs.

Connecting to MCU/MPU: The ZMCT103C current sensor module can be easily connected to a microcontroller or processor. The module has 4 output pins, two of which are to be shorted. The VCC pin is connected to the 5V of the MCU, and the OUT pin on the module is connected to the Analog input pin of the MCU/MPU. Once the connections are completed, the wire whose current is to be measured is passed through the donut-shaped ZMCT103C IC.

Module Configuration of a ZMCT103C Current Sensor
The ZMCT103C current sensor module consists of the donut-shaped IC which houses the secondary windings and acts as a transformer for current measurement. The module also consists of an OP07 operational amplifier which is connected along with a sampling resistor.

This is a basic circuitry used with the sensor, generally used to amplify the signals generated by the current transformer module.

Note: There is also a potentiometer on the ZMCT103C current sensor module which can be used to adjust the amplification factor.
