Overview:

DTSD637. DSSD637 series multi-function electric energy meter is a new type of electric energy metering product newly developed and produced by our company. This series of products are manufactured by advanced SMT process, with novel design, reliable quality, stable performance and perfect functions. This series of products adopts software adjustment error technology. The table integrates signal digital operation, digital filtering, digital error correction, and digital adjustment. It is not sensitive to temperature effects and has excellent stability. Accurate measurement of voltage, current, power factor, power, etc. can replace the role of a series of indicating instruments and transmitters. It is the first choice of modern electric energy metering products in the power supply sector.

The measurement part of this series of products fully conforms to the requirements of national standards such as GB/T17215.321-2008, GB/T17215.323-2008 and GB/T17215.322-2008; the performance conforms to DL/T 614-2007 "Multifunctional Electric Energy Meter" Standard requirements; communication protocols and communication link applications comply with DL/T645-2007.

Main features:

Forward and reverse active energy and maximum demand time-sharing metering function, record and save the previous 16 data.

Forward and reverse reactive power, four-quadrant reactive energy and maximum demand time-sharing metering function, record and save the previous 16 data.

It has real-time data measurement and recording functions such as voltage, current, and power.

It has event recording functions such as power failure, voltage loss, and current loss, and saves the current and previous 7 event records.

With voltage qualification rate event recording function.

With load curve recording function.

With power freeze function.

It adopts a Bianstone clock circuit, and has an optically isolated timing output port, and the output frequency is 1Hz square wave. The daily timing error is less than 0.5s/d (23+2℃), and the change with temperature is better than 0.1 s/(d℃).

With photoelectric isolation remote pulse output interface, power error test interface.

The automatic meter reading day can be set arbitrarily (1-28th), and the default is 0:00 on the 1st.

The maximum demand adopts slip type, the default demand period is 15 minutes, and the default slip time is 1 minute; and it can be set. The slip time can be set to 1, 2, 3, 5 minutes, and the demand period can be set to 5, 10. 15. 30. 60 minutes (if the demand period is set to 60 minutes, the slip time can only be set to 2, 3, 5 minutes).

There are 4 kinds of rates, 10 time zones, 4 sets of daily timetables and 10 daily timetables; weekly holidays and 10 public holidays can be freely set.

It adopts 8-bit large Chinese LCD liquid crystal display. Display items and display time can be freely set. Automatic wheel display and button wheel display can be set as required. The power display defaults to 6 integers and 2 decimals; and can be set.

Scope of use:

220V1.5(6)A～30(120)A This meter is the first choice of modern electric energy metering products for power supply departments, and is suitable for modern communities or enterprises and institutions.
