overview

The DT (S) S3666 three-phase electronic active energy meter is used for measuring active energy in power supply departments, factories, enterprises, commercial and agricultural power and lighting equipment. The meter adopts imported specialized large-scale integrated circuits, 16 bit A/D conversion, digital multiplier, digital sampling processing technology and SMT process. It is a new type of energy meter designed and manufactured according to the actual electricity consumption of industrial users. This instrument is used to measure AC three-phase active energy with a frequency of 50Hz, and the electricity is displayed on a LCD screen for intuitive reading and easy meter reading. It is equipped with infrared communication and RS485 communication, providing advanced and reliable measurement tools for three-phase energy measurement.

The metering module used in this meter can accurately measure three-phase positive and negative bidirectional active energy. Accurate, stable, reliable measurement, with good resistance to electromagnetic interference, low power consumption, high accuracy, anti-theft, wide range, long life and other characteristics.

All performance indicators of this product comply with GB/T17215.321-2008《Level 1 and Level 2 Static AC Active Energy Meters IEC62053-21：2003AC measuring equipment special requirements auxiliary word for ordinal numbersPart 21: Technical specifications for static active energy meters (Level 1 and Level 2).

Function and characteristic

1 Electric energy metering function

Energy metering function: metering the total active energy. Three phase power supply, one or two phases of power outage, measurement accuracy is not affected.

2 output interface

Equipped with optocoupler isolation active and passive pulse output interface.

3. Phase loss indication function

Use three light-emitting tubes to indicate whether there is a phase loss. The three light-emitting tubes represent phases A, B, and C. When a phase is missing, the corresponding indicator light will not light up.
