78M6610+LMU
Energy Measurement Processor for Load Monitoring Units
Autonomous Power Monitoring and Control for Embedded Applications
Part Details
- Four Configurable Analog Inputs for Monitoring Any Single-Phase Circuit (2/3-Wire)
- Supports Current Transformers (CT) and Resistive Shunts
- Flexible SPI, I²C, or UART Interface Options with Configurable I/O Pins for Alarm Signaling, Address Pins, or User Control
- Nonvolatile Storage of Calibration and Configuration Parameters
- Small 24-TQFN Package and Reduced Bill of Materials
- Internal or External Oscillator Timing References

The 78M6610+LMU is an 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 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, compensation, 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.
Applications
- Building Automation Systems (Commercial, Industrial)
