The PZEM-004T AC Voltage Current Module is an AC electrical measurement module designed to monitor key power parameters in single-phase AC circuits. It can be used to measure voltage, current, active power, and accumulated electrical energy, making it useful for energy-monitoring and power-management projects.
With a voltage measurement range of approximately 80–260V AC and a compatible 100A current transformer (CT), the module can monitor relatively high current loads without requiring the measured load current to pass directly through the low-voltage electronics.
