Product details
The DTSF825 electronic three-phase multi rate meter is designed using advanced energy metering chips combined with mature multi rate technology. It applies digital processing technology and SMT technology, and is designed, manufactured, and internationally advanced according to the actual electricity consumption of residents. All components in the meter are made of long-life and highly reliable electronic components, thus possessing the characteristics of long life and high reliability. This phenotype complies with the national standards GB/T15284-2002 "Multi rate (time-sharing) Electricity Meter" and GB/T17215-2002 "Level 1 and Level 2 Static AC Active Energy Meter", and the communication protocol complies with DL645-1997 "Multi functional Meter Communication Protocol". The product meets the technical requirements and communication protocol of electronic single-phase multi rate meter.
Function and Features:
1. Four rates (peak, off peak, flat, valley), twelve time periods, with a minimum time interval of 5 minutes between each period;
2. Store energy data for various rates for 12 months, including this month;
3. Advanced energy technology chips, high-performance CPUs, and PTC clock chips are used for electrical isolation;
4. Record the current total active power consumption and various rate electricity consumption, and save the data;
5. High precision, high reliability, strong overload capacity, low power consumption, and light weight;
6. Automatically accumulate and record battery working time;
7. Wheel display the current time, rate, total electricity consumption, and brother rate electricity consumption;
8. The communication protocol complies with DL/T645-1997;
9. It has pulse output with a pulse width of 80ms ± 20ms;
10. It has two levels of protection when writing data: password and programming switch, and automatically records the last programming time and number of times;
11. It is possible to set the meter number, bureau number, time period, rate, date, time, automatic meter reading date, password, cyclic display item, and starting power consumption;
12. Users can view the selected power parameters by tapping the wheel display button on the watch.
