Product Brief Introduction

 

DSSF8888/DTSF8888 three-phase electronic multi-rate watt-hour meter can metering active forward and reverse direction accurately, own the function of recording the max demand ,measure and process the voltage, current ,power etc parameter all the time. Own the function of time-sharing control, reading automatic, data storage of electric quantity and demand quantity ,the record of current operate state and event record etc.which is a ideal intelligent instrument of realizing time-sharing metering and checking working. This kWh adopt large scream LCD to display with the port of remote infrared, RS485 etc. This instrument  adopt advanced  super-low  low power consumption LSI and SMT technics to manufacture hi-tech products, which pivotal component adopt  known international brand long-life component ,which enhance the reliability and natural life of product. This product conform to GB/T 17215-2002 ,class 1 and class 2 static AC active kHz meter,GB/T 15284-2002  the special requirement of mufti-rate kwh meter,JJG596-1999 electric kwh examination rule, DL/T 614-1997 multi-function  kwh meter communication rule.
