DDSF825 Electronic Multi-rate Watt-hour meter

Summary



DDSF825 electronic multi-rate watt-hour meter using advanced energy metering unit and multi-rate cell design component,the application of digital sampling techology and SMT process,large0screen LCD display,with swparate infrared communication and RS485 communication interface.The table used to implement time-measurement,high accuracy,reliability,wide load,low-power,anti-interference ability and so on.







Characteristic



1.Measurement Function



a.Positive active energy measurement of time-sharing, and storing its data



b.Reverse active energy measurement, and stores its data





c.Active time-sharing maximum demand metering and timing, and stores its data



2.Multi-rate Function



Programmable 4kinds of rates,8 time.



3.Display Function



a.Time LCD display,6-bit integer,2decimal places



b.A significant feature of automatic rotation, display, time and order can be set, round was not more than 16 parameters



c.Display with push-button, display, time and order can be set to display no more than 16 parameters



4.Communication Function
