DDS6789 Single phase electric energy meter

DDS6789 is the world’s most advanced single phase electronic multi-tariff energy meter that combines advanced chip for energy measurement.

This meter have function of measurement by time-sharing executive, auto meory data in enact date, read and programme meter by hand-held terminal or PC, LCD display etc. The meter has RS485 comunication funtion.

Every function of this meter according with all the technical
requirements from single phase electronic multi-tariff energy meter conform to
electrical requirements as documented in GB/T
17215.321-2008/IEC62053-21:2003(Static meters for active energy (Classes 1 and
2),GB/T15284-2002(Multi-tariff energy meter particular requirements) and
communication protocol according to international standard
IEC1107/DL/T645-1997(Multi-function Watt-hour Meter Communication Protocol).

Features

1. Time measure positive and negative
power of active and store data, negative power count as per positive power into
electricity consumption.

2. Each of four periods has different rates (point period, peak period, smooth period and trough period). Every period of time can be programmed into 12periods of time and the minimum time interval is one minutes, period can over zero clock, setting from min to max.

3. By hand held unit FR from 10 Meters long
can read the meter and programme, set the funtion, infrared and RS485
communication Baud rate 1200.

4. Programme control, programming and
meter reading on site can be done by using the
infrared hand unit(HHU) with PC; RS485(option) meter reading.For protect
meter data security, meter programme adopt hareware and soft, hardware is
programme switch. Software is password. When switch open”Programmed allowed”
and input passwrod then programme meter. Programme switch not control to read
operation. Meter password have two type, one is programme password, another is
clear zero password.

5. Record
freeing data for 12 months.Power data freen store on hourly basis of any
specified date of 1-28 each month.

6. All memory data will be kept more than 10 years after power off.

7. It has pulse
output communication, pulse width:80ms±20ms, red LED for output impulse.

8. Correct time function, HHU password same as energy meter password, can
write any time by HHU, broadcast correct time operate
should be interval 1 month.
