Product Description
DTSD, DSSD1977 Type three-phase multi-function watt-hour meter
INTRODUCTION
DTSD, DSSD1977 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 cratt.
The performance index of the rneter accord with the technical requirements of national standard, such as GB/T 17215.321-2008"Class 1 and 2 Static A. C Active watt-hour Meter", GB/T 17215.322-2008 "Class 0.2s and 0.5s Static A. C Activewatt-hour Meter", and DL/T614-1997"Multi-functionwatt-hourmeter", the communicationagreement accord With DL/T645-1997.
It has function such as measuring each direction of active, reactive electrical quantity and demand quantity, two 485communication, awakening etc It has the advantageof stable 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 adaptation of 16 A/D switch, make voltage current sampling resolving power improvement, at the same time with application of DSP, to enhance the abllity ofcalculatingofelectrical quantity, to enhance the competition of product.
MCU apply to time-sharing counting and processlng all kinds of output, input data And measure the active, reactive power, max demard 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 operatinq parameters, record all kinds of data.
FUNCTION
Electric energy measurement, max demand record, Multi-tariff 1055 voltage and 1055 phase record, 1055 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.
