Three-phase multi-function table is set telemetry, remote, remote control in one of the intelligent power distribution
instrument. It uses the international advanced instrument-specific single-chip microcomputer, through the direct
sampling of the AC signal, after processing the relevant electrical quantity, while the instrument integrates
the switch signal input and output, local display, man-machine interface and digital communication interface,
so that the The instrument can independently complete a real-time monitoring of the amount of electricity at
a outlet interval. After the use of electricity users can more effectively carry out electricity monitoring,
improve energy efficiency.
