It accurately measures AC currents up to 5A with 0.2% linearity and offers adjustable analog output amplification up to 100x. Designed for industrial and IoT applications, it features robust 3000V isolation and operates reliably between -40°C and 70°C. This pack includes three modules, ideal for professional energy monitoring and automation projects. ## Description Description: The module is equipped with ZMCT103C series small high-precision current transformers and high-precision operational amplifier circuits to accurately sample and properly compensate signals. It is convenient for signal acquisition of AC power within 5A. The corresponding output analog AC signal can be adjusted. The required output voltage can be adjusted according to the potentiometer (adjusting the amplification ratio, the amplification range is 0-100 times), but the maximum voltage at the output (OUT) will not exceed 1/2 VCC. Parameters: Rated input current: 5A Rated output current: 5mA Change ratio: 1000:1 Phase difference: less than or equal to 20' (100Ω) Linear range: 0-10A (100Ω) Linearity: 0.2% Precision level: 0.2 Isolation withstand voltage: 3000V Working temperature: -40 ° C ~ 70 ° C Sealing material: epoxy resin Voltage: DC5-30V Package included: 3 x ZMCT103C 5A AC Current Sensor Current Transformer Module Review: I should have checked.
