Overview:

DTZY637 (configuration number is B2V2.0) three-phase cost-controlled smart energy meter is a new generation of intelligent high-tech energy metering products developed and produced by Jiangsu Shengde Electronic Instrument Co., Ltd., in line with GB/T17215.301-2007, GB/T17215. 321-2008, GB/T17215.323-2008 and DL/T614-2007 and other related standards for electric energy meters, using the DL/T645-2007 communication protocol.

Main features:

Electric energy metering function: The meter has six basic electric energy metering functions, including forward active function, reverse active power, and four-quadrant reactive power of each element of A, B, and C, as well as combined active, combined reactive 1, combined Reactive 2 The calculation function of these three types of combined electric energy.

Measurement function: This instrument can measure the apparent power, active power, reactive power, power factor of the composite element and each sub-element of A, B, and C, and can measure the voltage and current of each sub-element of A, B, and C. Grid frequency, and can display the direction of current, power and power factor.

Maximum demand metering function: The meter has six types of basic demand metering functions: forward active power, reverse active power, and four-quadrant reactive power. At the same time, the maximum demand for each type of basic demand is calculated according to the settlement cycle. and the time of occurrence of the maximum demand.

Time-sharing function: including time-sharing measurement, calendar and time-sharing, time-sharing scheme switching functions

Settlement function: The meter's energy metering data, maximum demand metering data and time-sharing data not only save the current data, but also store the historical data from the previous January to the previous December. The "month" of this function refers to the settlement cycle, and the settlement cycle of the instrument can be set by setting the settlement date.

Display function: The instrument adopts large-screen liquid crystal display, and has rich Chinese characters prompts, the display is intuitive and the viewing angle is wide.

Communication function: This watch has three communication ports: RS485 port, remote communication module (or second RS485), and far infrared port.

There are also event recording function, load curve recording function, freezing function, zero-clearing function, pulse output, LCD backlight function, light alarm function, power failure meter reading function, local and remote cost control functions, etc.
