Product Brief Of Introduction

The DTSF7666, DSSF7666 type three-phase electronic multi-rate watt-hour meter adopts the advanced special energy measuring chips and the multi-rate technology, using the date sampling and SMT technology. The product is designed and produced according to the practical situation of the dweller. AII the elements inside the meter have the feature of long-life,high-reliance. AII the indexes of the  meter accord with the standard of GB/T15284-2002 Multi­ rate(Time-sharing) Watt-hour Meter" and GB/T17215.321-2008.Class 1and 2 Static A.C Active Watt-hour Meter, the communication accord with DL/T645-1997 Multi-function Watt-hour Meter communication Rule.

Function and Features

- Each of hour periods has different rates (point period,peak period,smooth period and trough period).  Every period of lime can be programmed into 12 periods oftime and the minimum lime intervalis five minutes;

-AII the consumption date can be reserved for 12 months;

- The meter adopts the advanced energy measuring chips,high capability CPU and RTC clock chips;

- Recording the active electric quantity and the electric quantity under every rate,and reserved it;

- High accuracy, sensitivity and reliability, wide overload endurance, low power con-sumption and light in weight;

- Auto accumulate and recording the working lime of the battery;

- Display the present time, rate, total electric power and every rateelectric power;

- Communicate agreement accord with DLlT645-1997;

-It has pulse output communication pulse width:80ms±20ms;

-It adopts the password and program switch protection, recordingthe latest program time and degree;

- it can setup the meter number, bureau number, time-period, ratedate, time, meter reading time, password and the initial electricpower. 

The meter is highly precise, highly sensitive. Highly reliable wide load rang, low power loss, the power in double directions. Both positive and negative work can be measured in accumulated same direction. So it can prevent any power steeling, such as reverse steeling. live-earth wire steeling, short circuit and so on.
