4. Major function
Measure the AC active energy of positive direction and reversed direction,the energy of reversed direction will be measured according to positive direction.
Phase off indication founction: when phase off, the indicator is lit
Opposite phase indication founction: when active power show a negative balance, the indicator is lit
Adopt photoelectric isolated technology,which output pulse signal, power supply will be can instructed by light emitting diode.
Have RS485 Communication interface and Infrared Data Association(optional)
