Analog electricity meter module. The transformer measures AC current only. The module uses a TA12-100 current transformer to convert large-current AC signals into small-amplitude signals, enabling safe, low-level analog measurement. 3-wire electronic block interface, with supply input of 5V and GND. The S pin provides the analogue output voltage value. Jumpers allow selecting the parallel output to adjust the range of the analog output values. Benefits at a glance - Simple integration with 5V systems and ADC inputs - Adjustable output range via jumpers to fit different measurement needs - Safe, low-level analog signal derived from large AC currents - Based on a TA12-100 current transformer for reliable AC current sensing Practical applications - Home or small bench energy monitoring: read AC load current with a microcontroller or data logger - Power supply or inverter testing: monitor AC current on lines and convert to an adjustable analog signal for analysis - Lab experiments requiring scaled AC current measurements to feed into analog instruments or recording equipment
