Summary

DT (S) SF193 type three-phase electronic energy meter system of our latest products, in line with "GB/T17215.321-2008 AC measuring equipment - Part twenty-first: Particular requirements for static type electric energy meter (1 and 2)," GB/T15284-2002 "multi rate electric energy meter", "the special requirements of DL/T614-1997 multifunctional electric energy meter" DL/T645-1997, "multi function watt hour meter communication protocol" and other standards of the power industry of tariff requirements; the product can be used for measuring the reference frequency of the three-phase AC power grid in 50Hz, and can carry out a variety of rate and reverse power measurement. The utility model has the advantages of high precision, good reliability, wide load, low power consumption, straight error curve and strong anti-interference ability.

Main features

■The design and construction of the electric energy meter can ensure that it does not cause any danger under the rated condition

■It can be used to measure positive and negative active power, as well as peak, peak, flat and valley power.

■It has the function of measurement, which can measure the total, sharp, peak, flat, valley demand and demand time

■The electric energy meter has two kinds of communication modes, infrared and RS485, and the communication protocol accords with the DL/T645-1997 communication protocol of Multi-function Energy meter.

■The LCD display shows the total circulation, or by sharp peak flat valley and the total power last month, sharp peak, flat and valley electricity, convenient meter reading, power display is 5 bit integer, 2 decimal.

■Round display: electric energy meter can set the display items (less than 16), after power meter according to the set time to turn round the project and display data, first display code is displayed, then the contents of the display, as well as Chinese tips.

■Key display: electric energy meter can display the project settings button (less than 30), the page by pressing the button, the electric energy meter according to the preset key display display data. Display is also the first to show the code, after the display content. If you do not press the button will automatically enter the meter.

■After the power failure to maintain the normal operation of the battery.

■Energy meter using 3.6V, 1.2Ah high capacity lithium battery, the normal life of 10 years.

■Under the condition that the program switch is opened and the password is correct, the clock of the electric energy meter can be modified at any time.

■The programmable switch open, the correct password state, by a "handheld meter zero" command, can remove all of the electricity and electricity events.
