　　1 Product Introduction

　　Function:

　　This series of products adopts a DIN35mm guide rail installation structure, with a compact size, capable of measuring electrical energy and other electrical parameters, and can set parameters such as clock and rate periods. It has high accuracy, good reliability, and performance indicators that meet the technical requirements of national standards GB/T17215-2002, GB/T17883-1999, and power industry standard DL/T614-2007 for electric energy meters. It also has the function of outputting electric energy pulses; RS485 communication interface can be used to exchange data with the upper computer.

　　Application scope:

　　Suitable for sub metering of electricity in government agencies and large public buildings, and can also be used for energy management assessment in enterprises and institutions.

　　Electric pulse output

　　1) 1 channel, configurable and selectable (* value and) active or reactive power pulse output;

　　2) Pulse output width of 50mS, negative pulse; 3) Each pulse equivalent is: instrument voltage range * current range/2400000 degrees; 1.3.3 Communication Interface 1) Interface Type: RS-485 Interface. 2) Communication protocol:

　　The timing segmentation accuracy is too low (with a minimum segmentation of 5 minutes), making it susceptible to interference and difficult to adjust the time period. The usage function is single and cannot meet some special requirements in time of use billing. Currently, it has been basically eliminated and discontinued. This type of electric energy meter is connected to a quartz clock through wires to drive peak and valley electromagnetic counters at different time periods, displaying peak, valley, and total electricity respectively. Subtracting the peak and valley electricity from the total electricity is the electricity during normal time periods. Due to the poor reliability of this time-sharing billing energy meter. Early generation quartz clock controlled time division electric energy meter.
