IEC62056-21/42/46/53/61/62
FUNCTIONS:
Energy Measurement:
Measure reverse/forward active/reactive energy and energy of four Quadrants in different tariffs.
Can set the measurement ways of forward reactive and reactive power . Store the energy data of last 12 months.
Max. Demand:
Measure reverse/forward active/reactive Max. demand, and reactive Max. demand of four quadrants & its occurring time in different tariffs.
Tariff and Time Segments:
Able to set 8 tariffs, 14 time zones, 12 sets of time period list, 14 time periods and 13 holidays, holiday & weekend can be presented in different time periods.
Real Time Measurement:
Accurately measure voltage, current, active power, reactive power, apparent power, power factor and frequency etc.
Monitoring Record:
Record separately no phase, no voltage, over voltage, current unbalance and other relevant data of the last10 times.
Load Curve:
Support 32 types of curve, each curve has a different time interval. Max. Storage is 256Kb, can be extended to 2Mb.
Calculate and test if the voltage is ok, record four phase update rate in last four months.
Active and reactive pulse optical couple, real time clock pulse optical output, two route programmable reply output.
Energy Freeze:
You can freeze the energy by broadcast, and also freeze the energy at hour.
Standby Battery:
If there is power off, you can still read the meter by the button or Infrared function.
Communication Port:
RS485 and infrared communication port.
FEATURES:
Backup Time Segments Parameter: You can set a standby tariff period and effective time, to satisfy the client who needs to change the setting tariff plan.
Real Time Clock High Accuracy: Real time clock has temperature compensation function and it assures the clock error less than 0.5s/d. Under the high temperature and low temperature.
Three Phase Power Source Supply: Even there is only one phase works, the meter can keep running.
Good tamper capability.
