Overview

DT(S)SF193The three-phase electronic energy meter is our latest product, which meets the requirements ofGB/T17215.321-2008Special Requirements for AC Measurement Equipment21Part: Static active energy meter（1Level and2Grade)GB/T15284-2002Special Requirements for Multi Rate Energy MetersDL/T614-1997Multi functional electric energy meterDL/T645-1997The various requirements for multi rate meters in power industry standards such as the Communication Protocol for Multi functional Energy Meters; This product can be used as a reference frequency for measurement50HzThe three-phase AC active energy in the power grid can be measured at various rates and in reverse. Its characteristics are high precision, good reliability, wide load, low power consumption, straight error curve, and strong anti-interference ability.

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.

■It can measure the total active energy in both forward and reverse phases, as well as the peak, off peak, off peak, and off peak energy. Reverse phase energy can also be measured in both forward and reverse phases.

■It has demand measurement function, which can measure total, peak, flat, valley demand and demand occurrence time.

■Electric energy meters have infrared andRS485Two communication methods, communication protocol compliantDL/T645-1997Communication Protocol for Multi functional Energy Meters.

■adoptLCDDisplay item by item or cyclically display the totalSharpPeak, off peak, and off peak electricity consumption, as well as the total electricity consumption of the previous monthSharpPeak, flat, and valley electricity consumption, convenient for meter reading, with electricity displayed as5Bit integer,2Decimal places.

■Wheel display: The energy meter can be set with wheel display items(not exceed16item)After power on, the electricity meter will display data alternately according to the set rotation items and time. When displaying, the code will be displayed first, followed by the content, and there will also be Chinese prompts.

■Button display: The energy meter can set button display items(not exceed30item),By pressing the page turning button, the energy meter displays data according to the pre-set key content. The display also shows the code first, followed by the content. If the button is not pressed, the meter will automatically enter the wheel display.

■After a power outage, the clock is maintained in normal operation by the battery.

■The electric energy meter adopts3.6VThe1.2AhThe high-capacity environmentally friendly lithium battery has a normal service life of10Year.

■Under the condition that the programming switch is turned on and the password is correct, the clock of the energy meter can be modified arbitrarily.

■When the programming switch is turned on and the password is correct, the handheld device can issue the "meter reset" command to clear all electricity levels and usage events.
