Overview

DDSF193The single-phase electronic multi rate energy meter is a new generation of energy metering product developed and produced by our company in accordance with the relevant technical specifications of smart meters of State Grid Corporation of China. This product uses dedicated large-scale integrated circuits andSMTThe production process has functions such as energy metering, data processing, real-time monitoring, automatic control, and information exchange.The main performance indicators of the electric energy meter meet the requirementsGB/T 17215.211—2006General Requirements and Test Conditions for AC Measurement Equipment-第11Part: Measurement EquipmentGB/T 17215.321—2008Special Requirements for AC Measurement Equipment-第21Part: Static active energy meter（1Level and2Grade)GB/T 15284-2002Special Requirements for Multi Rate Energy MetersDL/T 614—2007Multi functional electric energy meterDL/T 645—2007The relevant requirements of standards such as the Communication Protocol for Multi functional Energy Meters.

Main functional features

■The design and structure of the electric energy meter can ensure that it does not cause any danger when used under rated conditions;

■Equipped with time-sharing metering function, the active electrical energy is accumulated and stored separately according to the corresponding time period, including total, peak, off peak, and valley electrical energy

■Having two sets of rate schedule, which can be automatically converted at the agreed time; Each set of rate support4Individual rate

■Equipped with far-infrared communication andRS485Communication function

■ The total, peak, average, and valley electricity levels can be displayed in a loop through the buttonsCurrently, on1moon-up12Monthly cumulative total electricity consumption and electricity consumption at various rates, convenient for meter reading, the power display is6Bit integer,2Decimal places

■ Record12The total electricity consumption on a settlement day, which can be measured through infrared andRS485Copy out the interface

■Record the total number of school hours (excluding broadcast school hours), recent10The time and operator code of the next school hour
