MAX78615+LMU Datasheet | Maxim Integrated

Isolated Energy Measurement Processor for Load Monitoring Units GENERAL DESCRIPTION The MAX78615+LMU is an isolated energy measurement processor (EMP) for load monitoring and control of any 2-wire single-phase or 3-wire split-phase (120/180°) AC circuit. It provides flexible sensor configuration of up to two MAX78700 (four analog inputs) and numerous host interface options for easy integration into any system architecture. The internal 24-bit processor and field upgradeable firmware performs all the necessary signal processing, pensation, and data formatting for accurate real-time measurement. Energy accumulation, alarm monitoring, and fault detection schemes minimize the overhead requirements of the host interface and/or network. The integrated flash memory also provides for nonvolatile storage of input configurations and calibration coefficients.
