Detailed Product Description
multi meter,meter,kwh meter,electronic meter
GeneralThree-phase electronic multi-function kWh meter adopts the advanced LSI, digital
acquisition 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 data processing for the customers` relevant tariff and demand,
It has 4 tariffs, 4 time intervals, 10 date segments, clock and 10-year calendar,
infrared remote programmable meter reading, RS 485 communication interface and etc.
functions. The specifications can meet the requirements of IEC62053-
22:2003,IEC62053-23:2003 and IEC62056-21<<Electricity metering-data exchange for meter
reading, tariff and load control-part21:direct local data exchange>>.
Technical characteristics
1. Time-of-use metering for forward and backward active energies.
2. Time-of-use metering for 4 quadrants reactive energies.
3. Time-of-use metering maximum electricity demands for forward and backward active
energies.
4. 4 tariffs, 4 time intervals, 10 date segments.
5. Functions of switch pulling and power off testing.
6. RS485 interface for PC communication; infrared communication, program setting and
reading with 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 preset
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.
