Product Description
DSSD722 type three-phase multi-function watt-hour meter is a modern advanced level meter which adopt large-scale integration circuit, apply number sampling processing technology and SMT craft.
The performance index of meter accord with the technical requirements of national standard, such as GB/T17215.321-2008 "Class 1 and 2 Static A.C Active watt-hour meter", GB/T17215.322-2008 "Class0.2s and 0.5s Static A.C Active watt-hour meter", and DL/T614-2007 " Multi-function watt-hour meter", the communication agreement accord with DL/T645-2007.
It has function such as measuring each direction of active,reactive electrical quantity and demand quantity , two 485 communication,awakening etc. It has the advantage of performance,high accuracy,easy operation.
Element
When watt-hour meter working, voltage,current pass sampling circuit, then the A/D switch transform it to number signal, send it to DSP for processing, with adaption of 16 A/D switch, make voltage current sampling resolving power improvement, at the same time with application of DSP, to enhance the ability of calculating of electrical quantity, to enhance the competition of product.
MCU apply to time-sharing counting and processing all kinds of output,input data. And measuring the active,reactive power,demand power accord to the period which are set in prior. It can display the data if needed, and can transmit the data by infrared or port 485 monitor the oprating parameters, record all kinds of data.
Function
-Electric energy measurement,max demand record,loss current record,over voltage record,owing voltage record,over current record,voltage qualified rate record,data scroll display,pressing-key display,power on,off record,check-timing on broadcast,alarming,programmable function,wave measurement function.
-Record present operation state of the meter
-Electric energy freezing
