Power and Energy

The MCP39F511N offers signed power numbers for

active and reactive power, import and export registers

for active energy, and four-quadrant reactive power

measurement. For this device, import power or energy

is considered positive (power or energy being

consumed by the load), and export power or energy is

considered negative (power or energy being delivered

by the load). The following figure represents the

measurements obtained by the MCP39F511N.
