 | Shanghai Jinling Co., Ltd. | | Product Detail | The multi-tatiff maximum demand watt-hour Meter in D(Z)F9 SERIES | Description:
| Product Class : Electronic Instrument·Electrician Instrument
The multi-tariff,multi-tariff and maximum demands watt-hour meters are intelligent type with electro-mechanical integration by adopting the modern electronic technique.Besides the performance of ordinary three-phase meter,they can also complete the energy measurement of four tariff,the maximum demand indication,load control,data transfer from distance etc.at continuous time or any time interval.They are mainly used in power plant,power station,substation etc.and measure the energy at peak-time,spare-time,control the maximum demands.These products are in line with the national standard GB/T15284-1994.
Construction and Feature
They are improved on the basis of three-phase inductive watt-hour meter and that consisted of infrared sensor,electronic multi-function register and infrared programmed part.
With running reliability,these products adopt the modern circuit that is anti-interfere.
Having been divided into ten time interval,the four tariff and can memory the four set of time interval and be changeable according to date.They set 1~2 days as work-off and can be set as tariff or time interval automatically for users.
With the accuracy of time switch so that the accuracy of the energy measurement and demand indication can be guaranteed.
The case is made of polycarbonate with the features of good seal,anti-impactive as weel as anti-flame and can be used at the ambient of –60~+1000C for long time and not easy aging.
The maters base on the inductive three-phase watt-hour meter in D86 series and type DS39,and the installation and connection of former three-phase meter are kept so that the installation and calibration tolerance with the adjustment and maintenance is very convenient.
The R power transformer with which the widely voltage range and good uniform
The maintain of power-off is more than 6 years(The life of battery is 10 years).
Memory automatically.
Impulse output interface with photoelectrical coupling,circulation display or meter reading function at interruption of power.
