How to select high-voltage metering meters for Hebei factories? What are the models of Hebei Power Peak Valley Flat Electric Meter? Where can I buy a three-phase high-voltage metering time-sharing meter in Hebei?
The three-phase three wire time-sharing electricity meter DSSF2026 has functions such as active power time-sharing measurement, reactive power measurement, infrared and RS485 port communication, etc. It adopts LCD display mode and a handheld meter reading microcomputer to set electricity parameters and collect electricity. It is an ideal measuring tool for implementing time-sharing billing for industrial, business outlets, and residential electricity consumption.
2. Main technical indicators:
● Operating frequency range: 50Hz ± 5%.
Accuracy level: active power level 1.0, reactive power level 2.0.
Reference voltage: 3 × 220/380V, 3 × 100V.
Rated current: 1.5 (6) A, 5 (30) A, 10 (40) A.
● Power consumption of the whole machine: ＜ 1.5W.
Clock error: ≤ 0.5s/d (23 ± 3 ℃).
● Backup lithium battery service life:>10 years,
Continuous working time: ≥ 3 years.
● Working environment temperature:- 10 ℃ to+55 ℃.
● Extreme operating temperature:- 25 ℃ to+70 ℃.
3. Main functions:
Electricity metering: measures the cumulative positive active, peak, off peak, off peak, and valley electricity of the current and previous 6 months, as well as the total positive reactive electricity of the current and previous 6 months, where both positive and negative cumulative reactive electricity are counted as positive metering.
Maximum demand measurement: It can measure the current and previous 6 months' positive (positive and negative cumulative positive measurement) total maximum active demand and its occurrence time.
● Rates and time periods: Four rates (peak, off peak, off peak, and off peak), up to 12 time periods can be set per day, and time periods can be set across zero.
Parameter programming: It can set the meter number (address), time period, calendar, clock, month end meter reading date, password, and start reading of active and reactive energy.
● It has a load curve recording function, which can record electricity and active power, and has a phase failure recording function, including the start time, end time, and cumulative time of phase failure.
