Detailed Product Description
Product Brief Introduction
Three-phase electronic multi-function kWh meter adopts the advanced LSI, digital processing and SMT techniques. For the purpose of meeting the real application situation in the Chinese industry customers needs, this product is designed and manufactured as the international advanced new generation of electronic multi-function kWh meter. The product can accurately measure forward and backward active and reactive energies, active and reactive powers, parameters of voltage, current and frequency, It can provide digital processing for the customers` relevant tariff and demand, It has 4 tariffs, 4 time intervals,10 tariff segments, 10 date segments, clock and 10 year public holidays,remote infrared or via RS485 programmable meter reading, and remote pulse output etc.The specifications conform to the requirements of IEC62053-22:2003,IEC62053-23:2003 and IEC6205621
Function and feature
1. Time-of-use metering for forward and backward active energy.
2. Time-of-use metering for 4 quadrants reactive energy.
3. Time-of-use metering maximum electricity demands for forward and backward active energy.
4. 4 tariffs, 4 time intervals, 10 date segments.
5. Functions of switch pulling and power off detection.
6. RS485 interface for PC communication; infrared communication, program setting and reading by palm computer set; infrared remote reading (manual recording).
7. LCD display for various parameters setting and measurement data.
8. Realization of parameters polling display. The polling parameters (no more than 32 items) and time can be preset. The order of the polling parameters can also be set arbitrarily.
9. The measurement RMS of voltage, current and frequency
10. Functions for programmable prohibit, data clear and demand reset.
11.Customer may select the inner power off reading mode which can, in the condition of power off and; no outer direct power supply, do meter reading with infrared remote controller for more than 1000 times readings. This reading mode does not influence the life of data saving battery
