Function type | Features |
Electricity measurement | Combined total active power metric, combined active power metric for each rate Positive and negative total active power measurement, forward and reverse active power measurement for each rate Combined reactive power 1 total power measurement,combined reactive power 1 power measurement at each rate Combined reactive power 2 total electricity metric, combined reactive 2 power metric at each rate Four-quadrant total reactive power measurement, four-quadrant power measurement for each rate Total apparent electricity metric, apparent electricity metric for each rate |
Demand statistics | Real-time demand for active and reactive power, current and maximum demand records for the last 3 settlement days |
Monitor | Voltage, current, active power, reactive power, apparent power, power factor, frequency |
Harmonic statistics | 2~31 harmonic |
Time-sharing billing | Can set 4 rates, 12 time periods, 8 daily timetables, 12 annual time zones, 90 public holidays, weekly holiday timetables Prioritize the implementation of the public holiday timetable, followed by the weekly holiday timetable, Finally execute the timetable used by each time zone With two sets of time zone tables and two sets of daily time slots With two sets of tariff rates and two sets of ladders Electricity measurement and maximum demand data include time-of-use rate data |
Prepaid* | Prepaid function: pay first, then use electricity, the device will automatically close after recharging The meter can set up to 4 tariff rates and 4 step tariffs. The step tariff is the relative incremental tariff of the tariff rate. The current billing tariff= the current tariff rate + the current step tariff. Overdraft function: when the electricity bill is 0, the user is allowed to use a certain amount of overdraft, and the amount of overdraft can be set |
Settlement | Automatically save the current power and demand according to the set settlement time Save the last 12 months of settlement electricity and the last 3 months of settlement maximum demand The settlement date can be arbitrarily selected between the 1st and 28th of each month When the power-off state crosses the settlement date, the meter will supplement the cross-month settlement data |
Freeze | Timed freezing function, which can generate event records and save the data of the last 3 cycles of timed freezing Instantaneous freezing function, can generate event records, the instrument can save the last 3 instantaneous freezing data Appointment freeze function, which can generate event records, and the instrument can save the last 2 appointment freeze data |
