ZMCT103C Single Phase AC Current Sensor – 5A Transformer

The ZMCT103C Single Phase AC Current Sensor is a precision current transformer module designed for accurate measurement of alternating current up to 5A. It features a built-in 1000:1 micro current transformer with high linearity and 0.2% precision, providing a proportional 5mA output signal for signal conditioning and monitoring circuits. The module ensures 3000V insulation voltage for safe electrical isolation between measurement and control systems. Encapsulated in epoxy resin for stability and durability, it operates reliably within a temperature range of -40°C to +70°C. Ideal for energy monitoring, power metering, and AC load measurement applications.
