1. Overview:

DT(S) S-type three-phase electronic active power meter(hereafter:3 phase electronic meter), 

used in power supply departments, factories, enterprises, commercial, agricultural power, 

lighting equipment of active power metering, this table adopts imported special large-scale integrated circuit, 

16 bit A/D conversion, digital multiplier, digital sampling processing technology and SMT process, 

A new type of electric energy instrument designed and manufactured according to the actual situation of industrial users. 

Used for measuring AC three-phase active power with frequency of 50Hz, and the power using liquid crystal display,

 intuitive reading for easy meter reading, this instrument with infrared communication and RS485 communication,

 to provide advanced and reliable measuring tools for three-phase power measurement.

The measuring module used in this table can accurately measure the positive and negative bidirectional active energy of the three phases. 

Accurate measurement, stable, reliable, with good anti-electromagnetic harassment, low power consumption,

 high accuracy, anti-theft, wide range, long life and so on.

The performance indicators of this product are in line with the technical indicators of the electricity meters set by GB/T17215.321-2008 

"Level 1 and 2 stationary AC Active power Meters", DL/T 645 -- 1997 "Communication Protocol for Multifunctional electricity Meters" 

and DL/T 645 -- 2007 "Communication Protocol for Multifunctional electricity Meters".

2. Main functions of 3 phase electronic meter:

2.1 Electric energy metering function

Measure total active electric energy. Three-phase power supply, one or two phase power off, the measurement accuracy is not affected.

2.2 Pulse output interface

With an optically decoupled active power passive pulse output interface, pulse width of 80ms.

2.3 lack of phase indication function

Three light tubes are used to indicate whether there is A lack of phase. The three light tubes respectively represent A, B and C.

 When a phase is lack of phase, the corresponding indicator light is not bright.

2.4 Communicating function

With infrared communication interface and RS485 communication interface, convenient for users to read power data through

 the communication interface, convenient and reliable.

Baud rate: 1200 for infrared communication and 1200 for RS485 communication by default. The baud rate can be changed.

2.5 Relay control function (extensible).

2.6 Outage display function (extensible)

2.7 Display total power data (without power parameter meter).

2.8 Instrument LCD display, wheel display meter number, power quantity, voltage, current, active power parameters, 

power display 10 seconds, other data wheel display 5 seconds (with power parameter instrument)
