Functions:
＃ 1-4 fee rates, 1-10 time periods per day,
1-10 time zones per year, 1-2 holidays per week, public holiday
schedules for 10 years.
＃ Measuring the active and reactive total
and each rate electrical energy, maximum demand and the time
occurred, total and each rate energy of 1-4 quadrants.
＃ Record the cumulative time, times of each
phase broken, the active, reactive cumulative energy in phase broken
period, starting and ending time of the latest, broken and the
latest 64 times of power-off.
＃ Record the load curve in load
representative day mode and load curve record mode, the interval can
be setted.
＃ LCD display.
＃ Four displays mode: pause, cycle, query
and continuous display, the display content, sequence and interval
period can be choose.
＃ Programming and reading the meter by PR
300 infrared meter-reading unit and hand-hold unit, and RS-485 port
to remote meter-reading and programming, support the electrical
energy broadcast frozen instructions by RS-485 field bus.
＃ Record the reset times, time and
cumulative programming times, the latest programming time and unit
code of programming.
＃ Communication protocol is jinque protocol,
which meet the requirements of DL/T 645-1997 (States standard
referred IEC 1107) , and can be set to be compatible with all sorts
of protocols.
＃ Pulse output is 3 or 4 optical coupling,
each can be set to output different content individually.
