78M6610+LMU  
Energy Measurement Processor  
for Load Monitoring Units  
FEATURES  
GENERAL DESCRIPTION  
Four Configurable Analog Inputs for  
Monitoring Any Single-Phase Circuit  
(2/3-Wire)  
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.  
Supports Current Transformers (CT) and  
Resistive Shunts  
Flexible SPI, I2C, or UART Interface Options  
with Configurable I/O Pins for Alarm  
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.
