Prepayment Single-phase Smart Electricity Meter

The prepayment single-phase smart electricity meter series is applicable to AC single-phase active electricity with a measurement frequency of 50 Hz, and its performance conforms to the technical requirements of GB17215.321-2008. The meter can sample live and neutral currents at the same time, having a liquid crystal display and multiple communication modes and supporting the 698 object-oriented data exchange protocol (or DL/T645-2007 protocol). It realizes the prepayment function via remote or local modes.

The technical specifications of the electricity meter are in line with the following standards:

Object-Oriented Communication Protocol (DL\T698.45 )

Electricity Information Collection and Management System (DL\T698-2010)

Functional Specifications of Smart Electricity Meter (Q/GDW 1354-2013)

Type Specification of Single-Phase Smart Electricity Meter (Q/GDW 1355-2013)

Technical Specifications of Single-Phase Smart Electricity Meter (Q/GDW 1364-2013)

6. Basic error: in line with the requirements of GB/T17215.321-2008.

7. Working environment: The electricity meter shall be installed in a dry and ventilated environment at a height of 1.8 meters where is free from corrosive gases. The temperature shall be kept -40°C to +70°C and the relative humidity shall not exceed 85%.

1.It has the metering functions of positive and negative active electricity and time sharing counting.

2. The clock is equipped with the built-in hardware clock circuit with temperature compensation function, as well as functions of calendar, timing, and automatic conversion of leap year. The broadcast timing is not limited by password code and hardware programming switch;

3. It supports rates of four time consumption including sharp, peak, shoulder and off-peak.

4.It can clear the data such as electric energy, freezing amount, event record, load record stored in the electricity meter.

5. It has two-way total electricity and rate electricity data stored for 12 settlement days. In the case of a power outage of the meter, all data related to settlement shall be kept for at least 10 years, and other data for 3 years.

6. It has the time freezing, instantaneous freezing, daily freezing, appointment freezing, and whole-point freezing functions, and the freezing contents and identification are complied with DL/T 645-2007 and the file requirements.

7.It can record the total number of power outage, the total number of programming, the total  timing hours, the total number of opening the meter cover, and permanently record the time to clear event and energy data of the electricity meter.

8. It has RS485 communication and infrared communication functions under the DL/T 645-2007 Agreement and its filed documents.

9. It has electric energy pulse output and multi-function signal output functions. 0

10.It has two display modes, i.e. automatic circulation and pressing of keys.

11.The meter has the dual protection function of programming switch and programming password

12.The implementation of prepayment function can be divided into local and remote modes.

13.It has two sets of price ladder, and another price ladder can be started at the designated time point.

14.The meter can be waked up by pressing a key for reading data under the power outage state.

15.When the electricity meter is used to set the parameters, pre-store the electricity fee, write back the information, and deliver the remote control command via the solid media or virtual media, the security authentication like passwords or ESAM module must be passed to maintain the safe and reliable data transmission.
