 | Shanghai Jinling Co., Ltd. | | Product Detail | Multi-tariff watt-hour 6 meter(DDF502,DDF9,DDF981,DTF502) | Description:
| Product Class : Electronic Instrument·Electrician Instrument
Type DDF502,DDF981 and DDF9 single-phase and type DTF502 three-phase multi-tariff belong to intelligent integrated electromechanical meter with monolithic processor.They are improved on the basis of inductive single-phase watt-hour meter and boast with not on the all basic functions of other ordinary single-phase and three-phase watt-hour meter,but also that of two~four tariff,even have the ability of indicat of the energy at different time interval,such as season,time interval and holidays etc. In households,factories and entertainment sites etc.and already become the important meter for department of energy-supply.These products comply with national standard GB/T15284-1994<<multi-rate(time-of-use_watt-hour meter>>and technique stipulation for single-phase multi-tariff watt-hour meter in Shanghai Electricity Network.
Construction and Feature
Type DDF502 and DDF981 single-phase multi-tariff watt-hour meter are improved on the basis of inductive single-phase long-life meter FD95 and DD981.Type DTF502 three-phase four wire multi-tariff watt-hour meter is improved on the basis of inductive three-phase four wire meter DT862.These products adopt SCM(Single chip micycoco)as a main controllable module and designed by adding clock circuit and double registers.With its infrared communication interface it can charge the power bill in the time consumptions of off peak,shoulder by setting up time consumptions in the meter’s clock.
Type DDF9 single-phase sariff watt-hour meter is improved on the basis of type DD862 inductive meter and consists of infrared receiver,electronic multi-function counting device and infrared program device etc.It adopts the modern soft,hard circuits which is ati-interfere,LCD display and Chinese word indication,photoelectrical coupling output,infrared remote control and the life of battery is 10 years.
