Multifunctional power meter features

The multifunctional power meter is a multifunctional power meter with functions of programmable measurement, display, digital communication and energy pulse transmission output. It can complete power measurement, energy calculation, data display, acquisition and transmission, and can be widely used in substation automation. , distribution automation, intelligent building, internal energy measurement, management, assessment.

Multifunctional power meter features

1) Time-divisional measurement of four-quadrant reactive energy, positive and negative active and reactive power rates and maximum demand and their occurrence time, measurement of active and reactive total energy, and energy data stored for 3 months.

2) Programmable 4 rates, 12 periods, 5 daily schedules, 4 time zones, 12 public holidays and 3 days of Spring Festival.

3) It has a standby time function, and records the power data and the total number of switching times when the standby time period was last switched.

4) The external clock chip has calendar, timing, and annual automatic switching functions, and it also has temperature compensation.

5) Wide-temperature and large-angle LCD display, with automatic wheel display and button display.

6) With two RS485 interfaces and one infrared communication interface, the three parties communicate at the same time without disturbing each other.

7) With multi-function output function, it can achieve 1Hz clock, demand cycle replacement signal, time switching signal, overload trip and other functions.

8) With event recording functions such as loss of voltage, phase failure, loss of current, overvoltage, undervoltage, overcurrent, voltage pass rate, stop calls, programming, demand clearing, and broadcast timing.

9) Real-time measurement of A, B, C three-phase voltage, current power and other effective values ​​and current frequency.

10) With wake-up button wake-up, infrared and light wake-up functions, light wake-up is optional (3 days after power failure) and can wake up to wake up infrared meter reading.

11) With fault information prompt, alarm (liquid crystal, report lamp, buzzer) function.

12) With monthly (settlement) positive active meter function.

13) With the load representing the function of the daily power record.

14) It has the functions of instant freezing, zero freezing and time zone conversion and freezing.

15) With event package (up to 100 records). The time when each event occurs can be recorded in order, and the data can be copied back through the PC.

16) Optional load curve recording function.

17) Optional open cover, cover record function.

18) Optional three-phase current detection without voltage (power failure within 3 days).
