Current transformer works as a low-power single-phase transformer, operating in a state close to a short circuit. Dedicated for higher currents measurement by measuring instruments with smaller measuring ranges (ratio 1: 1000). The module doesn't require a measured circuit cut. Just put the wire with current you want to measure through the sensor hole. Based on ZMCT103C current sensor. High precision op-amp circuit board, do accurate sampling for the signal and appropriate compensation, and other functions The module can measure up to 5A current. Technical data: Insulation resistance: 4500V PCB board size : 38 (mm) x18.5 (mm) Working voltage: DC5-30V https://elecena.pl/product/22624721/5a-ac-current-sensor-module-ammeter-ampere-meter-zmct103c 2023-02-23 https://elecena.pl/product/22624721/5a-ac-current-sensor-module-ammeter-ampere-meter-zmct103c 2024-12-16 https://elecena.pl/product/22624721/5a-ac-current-sensor-module-ammeter-ampere-meter-zmct103c 2025-10-26 https://elecena.pl/product/22624721/5a-ac-current-sensor-module-ammeter-ampere-meter-zmct103c 2025-10-28
