This module provides precise, galvanically isolated current measurement within a range of ±30 A and voltage up to 480 VRMS, providing RMS, instantaneous, and active, reactive, and apparent power readings. Equipped with an I²C interface, 4-pin JST SH connectors, and 2.54 mm pins, it allows for easy integration with Qwiic, STEMMA QT, and standard microcontrollers. Configuration stored in EEPROM allows for defining address and overload thresholds. The sensor offers three voltage measurement ranges (120 V - default, 240 V, 480 V RMS) and the ability to detect overvoltages. Built-in protection and low conduction resistance ensure safe and accurate measurements. Pololu 5410
