DDSF5558 Single phase multi-tariff energy meters is a kind of smart meter, it can measure energy consumption at different period.

Application

Forward and reverse energy measurement: accurately measure forward and reverse power, With standard RS485 Interface and optics interface. Communication agreement meets IEC62056-21 or DL/T645.4, Eight tariffs eight period of time. It can record 30 times abnormity events, like power off case open and so on. Forward energy measurement includes the reverse active energy and can store separately. Also it has anti-tamper as well as display and record load curve.5.&nbsp, Measurement in wide range and good ability in overload.(multi-tariff meter, electricity meter, kwh meter, power meter)

When meter is working,, after voltage and current get sample from sampling circuit, then enter special power chips, which will transform it to signal and send the signal to CPU to calculate. As CPU is to calculate energy at different tariffs and dealing with all kinds of data according to the time period which has been set in advance, the meter will display all kinds of data according different needs by infrared or RS485 to communicate , and can record and store kinds of data.
