Overview:

DT(S)S3666 three-phase electronic active power meter( hereafter: 3 phase 4 wrie electronic energy meter), 

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

 lighting equipment of active power measurement, the meter adopts imported special large-scale integrated circuit, 

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

According to the actual situation of industrial users to design, manufacture of new electric energy meter. 

It is used to measure the AC three-phase active power with a frequency of 50Hz. 

The liquid crystal display is adopted to make the reading intuitive and easy to read. 

The instrument is equipped with infrared communication and RS485 communication, 

providing advanced and reliable measurement tools for three-phase power measurement.

The metering module used in this meter can accurately measure the three-phase positive and negative bidirectional active energy. 

Measuring accurate, stable, reliable, with good anti-electromagnetic harassment, low power consumption, 

high accuracy, anti-electricity theft, wide range, long life and other characteristics.

The performance index of this product conforms to GB/T17215.321-2008 "Level 1 and Level 2 static AC active power meter",

 IEC62053-21:03 AC measurement equipment special requirements 

Part 21: static active power meter (level 1 and level 2) to the technical index of the meter.

Functions and features:

1 Power metering function

Power metering function: measure the total active power.

 Three-phase power supply, one or two phase power off, measurement accuracy is not affected.

2 Output interface

Isolated active and passive pulse output interface with optical coupling.

3 Lack of phase indication function

Three light emitting tubes are used to indicate whether there is A lack of phase. 

The three light emitting tubes represent three phases A, B and C respectively

FAQ:

What is a 3-Phase electric meter?

The 3-phase electric meter is used for measuring the power of three-phase electrical supply, 

most commonly for commercial use.

What does a three-phase power meter do?

A 3-phase power meter / 3-phase power analyzer, also called a three-phase power meter,

 can measure a variety of electrical parameters, from current and voltage to resistance, continuity and beyond.

What is difference between single-phase and three-phase meter?

One key difference between single-phase vs. three-phase is that a three-phase power supply better accommodates higher loads. 

Single-phase power supplies are most commonly used when typical loads are lighting or heating,

 rather than large electric motors. Single-phase systems can be derived from three-phase systems.
