1 Introduction
The Outlet Measurement Unit Model OMU1-S-WW (OMU1) is a low-cost power monitor employing the
Teridian 78M6612 SOC, a single-phase power and energy measurement IC supporting up to two outlets.
The 78M6612 IC monitors the AC line voltages and load current. The embedded demo firmware
calculates the RMS line voltage and RMS load current, Watts, VA, VAR and power factor for a single
outlet. Access to real-time data in the 78M6612 is available via a serial interface to a PC using a
Command Line Interface (CLI). A USB interface on the OMU1-S-WW provides the serial connection and
DC power to the 78M6612.
