Step into the world of high-precision current sensing with Kunkune’s ZMCT103C Current Sensor Transformer Module. Designed for those who demand accuracy without compromising on size, this module is a must-have for every electronic enthusiast in the UK.

ZMCT103C Key Features:

  • Compact Yet Powerful: Despite its small size, the ZMCT103C boasts impressive specifications.
  • Current Ratio: 5 A:5 mA, ensuring precise measurements every time.
  • High Rated Primary Current: Operates efficiently at 50/60 Hz with a 5 A rating.
  • Transformer Turns Ratio: A remarkable Np:Ns = 1000:1.
  • Safety First: With an isolation voltage of 4500V and epoxy encapsulation, it’s built for protection.
  • Onboard Sampling Resistor: Drops voltage to manageable levels for diverse applications.
  • Wide Operating Temperature: Functions seamlessly from -40 to 85 °C.
  • Extended Pin Length: Secondary coil (encapsulation) pin length exceeds 3mm.

ZMCT103C Pin Configuration:

  • Ground (G): The module features two ground pins, both of which should be shorted and connected to the MCU’s ground.
  • Signal Out: Connect this to the Analog input pin of your MCU/MPU.
  • VCC(+5V): Link this to the 5V of your MCU.

Special Mention: The ZMCT103C module comes with a unique donut-shaped IC design. To measure current, simply pass the wire through this IC. Additionally, an onboard potentiometer allows users to adjust the amplification factor, offering flexibility in applications.

Additional Features:

  1. Equipped with an onboard precision micro current transformer.
  2. Features a high-precision op-amp circuit board for accurate signal sampling, compensation, and more.
  3. Capable of measuring up to 5A current, with adjustable output analog quantity.

Dimensions: A sleek size of 38 x 18.5 mm.
