 | Shanghai Jinling Co., Ltd. | | Product Detail | ingle-phase multi-tariff static watt-hour meter | Description:
| Product Class : Electronic Instrument·Electrician Instrument
Type DDSF503(DDSF503a),DDSF982 and DDSF983 single-phase multi-tariff static meter belong to intelligent electronic energy measuring meter which are lately developed by us and the brand new energy measuring meter which can change the system of electricity-using at the moment effectively and control,adjust the electro-load.
These products comply with the national standard GB/15284-1994<multi-rate(time-of-use)watt-hour meter>,GB/17215-1998<Alternating current static watt-hour meters for active energy(classes 1 and 2)>and<the technical criterion for multi-tariff watt-hour meter in electricity network of Shanghai>.They are the appointed watt-hour meter for the rebuilding of electricity net of Shanghai.
Construction and Feature
Type DDSF503 and DDSF983 single-phase multi-tariff watt-hour meter are the intelligent watt-hour meter with the features of low product cost,high load and low starting current etc.which produced with AD7755 integrated chip of electric energy measuring that newly produced by company ADI.These products provided with RS485 communication port so that can set eight time intervals to the clock inside and realize the measurement at shoulder,peak time.
With the features of low product cost,high load and low staring current type DDSF503a single-phase multi-tariff watt-hour meter is novel intelligent watt-hour meter which adopts measured integrated chips.This product adopts the method of outputting the impulse from meter’s specialized chip to direct drive the register so that it can separate other circuits and has the features of strong anti-interference and reliability performance.The eter can measure electricity in the time consumption of off peak,shoulder by stting up eight time consumptions in the meter’s clock.
DDS982 single-phase static meter consists of long-life and pellet components and liquid crystal display with its features of novel design,high load(times),lower loss,small starting current,infrared communication interface and meter reading automatically.The meter can set up many parameters in advance to charge power bill in four tariffs,ten time consumptions,unidirectional registered fee for time-of-us.
The main technique parameter
1) adopting the infrared communication method to set time consumption in the meter’s clock or set other parameters
2) range for limit of working voltage:70%~120%Ub
3) reference temperature:230C±20C
4) RANGE FOR LIMIT OF WORKING TEMPERATURE:-10~550C
5) The accuracy of time error per day,under reference.
6) Reserved battery can maintain over ten years and parameters of EEPROM will be reserved over forty years when electricity is cut off
7) Pulse output wave:80±20ms
8) High electric level:>0.9VD
Low electric level:≤0.9V
Pulse output wave form is actual square-wave pulse width 80±20.
9)error in changing time consumption: ≤0.1s
