Main functions

1. Energy measurementIt can meas ure the forward and reverse electric quan tity,display the measurement and accumulation of reverseenergy and forward energy, also can indicate the reverseenergy amount. Meanwhile, it can prevent the electricitybeing theft by reversing the current.2. Detection interfaceThere is a detection terminal of photoelectric isolationand pulse output, for checking the meter and collectingthe energy.3. Communication functionThe power line carrier communication is realized bythe software spread-spectrum mode, with high accuracyand reliabil ity and strong reading stability. It supportsthe reading and frozen data by the low voltage powerline carrier communication mode or performs the realtimereading of active power and watt-hour meterconstants.4. Relaying functionMutual automatic relaying function
