4th Floor, Building C, Incubation Building, No. 229 Tongzipo West Road, Yuelu District, Changsha City, Hunan Province

overview

Weisheng DSSD331-U9 three-phase three wire energy meterSuitable for settlement gateways of regional power grids, provincial power grids and other high-voltage level power grids, power generation gateways of photovoltaic, wind power, hydropower and other power sources, as well as metering points of electrified railways with frequent load changes.

main features

The so-called multifunctional electricity meter refers to an electric energy meter that not only measures active (reactive) power, but also has two or more functions such as time-sharing and measuring demand, and can display, store, and output data.

Product advantages

1、 Large screen, wide-angle LCD display

High definition large screen machine with backlight option, large font display, clear data reading at a glance
2、 Supports dual RS485 communication and far-infrared communication

Dual RS485 communication has the characteristics of high communication speed, long transmission distance, and rich data

3、 Three major energy metering functions
1. Thirteen month historical data freeze record

2. Record segment phase, loss of pressure and loss of current events

3. Record demand and occurrence time

major function

● Two way air contact electrical pulse and LED electrical pulse indicator light output, alarm indicator light output.

Two RS-485 and one far-infrared communication interface, with independent channels.

Time division measurement of positive and negative active power, four quadrant reactive power, combination 1, and combination 2 reactive power, with the ability to set any combination of four quadrant reactive power.

Time division measurement of positive and negative active and reactive power demand and occurrence time.

8 rates, two sets of time periods for primary and secondary, dual clock backup, automatic error correction, capable of recording 13 months of historical records.

6 types of data recording load curves can be set, with a capacity of up to 2M bytes (optional 4M bytes).

Measurement function: Measure the voltage, current, apparent power, active power, reactive power, power factor, phase angle, and frequency of phases A, B, and C.

Record various events such as voltage loss, current loss, total current loss, voltage qualification rate, reset, clearing demand, programming, timing, power on, overvoltage, reverse phase sequence, and cover opening.

● Dual backup data storage, with self checking and error correction functions, with internal card error, clock error, voltage reverse phase sequence, loss of voltage, overvoltage, loss of current, and battery undervoltage fault alarm functions.

● Equipped with anti-theft electricity opening detection function.

After a power outage, the display can be awakened through buttons, and after awakening, meter reading can be done through LCD display.

Adopting switch mode power supply and AC/DC adaptive auxiliary power supply, the auxiliary power supply is given priority power supply after power on;

Record various frozen data to form a graphical analysis of abnormal electricity consumption consisting of event records, load curves, and frozen data;

The three-way optocoupler empty node can choose to output individual or three in one second pulse, demand cycle or slip time, and time period switching.
