3.9 Operation principle
As shown in figure 3, the current and voltage of power covered into small signal separately and input into a special measurement IC, after a series of process such as multiplication calculation etc. and then output energy pulse, whose frequency is in direct proportion to the supply power, to the microprocessor unit (MCU). The MCU calculate and process energy impulse to perform the power metering and load control functions etc. The LCD displays the total credit and remained credit etc. relay tripping off indirect shows the meter operation state.
