TE73 SG-2-3 230/400 V, 10(100) A three-phase electricity meter with GSM/GPRS modem
⚡ The TE73 SG-2-3 is a multifunction electronic meter designed to measure active and reactive energy in a three-phase four-wire network.
It supports direct connection up to 100 A per phase and transmits readings through a removable GSM/GPRS communication module.
🔤 Model designation
- S — three-element, four-wire version;
- G — removable GSM/GPRS module;
- 2 — 10(100) A current rating;
- 3 — 230/400 V voltage rating.
🔌 Main electrical ratings
- number of phases — three;
- network — three-phase, four-wire;
- rated voltage — 230/400 V;
- current rating — 10(100) A;
- maximum current — 100 A per phase;
- frequency — 50 Hz;
- connection — direct.
No external current transformers are required.
📡 GSM/GPRS transmission
The meter transmits readings through a cellular network directly to the receiving server.
The system requires:
- an active SIM card;
- cellular-network coverage;
- correct APN settings;
- the server address and port;
- registration in the AMR platform.
The GSM/GPRS version does not require a PLC concentrator, but it does require a SIM card and cellular coverage.
🕒 Multi-tariff measurement
The meter supports at least four tariffs, allowing consumption to be separated by time of day and day type.
🎯 Accuracy
- active energy — class 1.0;
- reactive energy — class 1.0;
- meter constant — 1000 imp/kWh;
- starting current — approximately 0.04 A.
🔗 Communication interfaces
- GSM/GPRS cellular communication;
- RS-485 wired digital interface;
- optical port for local reading and configuration.
💾 Memory and archives
Tariff readings, load profiles and event records are stored in non-volatile memory and retained during power outages.
🚨 Monitored events
- meter or terminal-cover opening;
- power failure;
- overvoltage or undervoltage;
- power overload;
- reverse-current direction;
- incorrect wiring;
- external magnetic influence;
- low internal-battery condition.
🌡️ Operating conditions
- normal operating temperature — −25 to +60 °C;
- permitted limiting range — −45 to +70 °C;
- ingress protection — IP54.
📦 Package contents
- TE73 SG-2-3 electricity meter;
- removable GSM/GPRS module;
- terminal cover;
- product passport;
- operating manual;
- certificate;
- factory packaging.
✅ Key advantages
- three-phase 230/400 V measurement;
- direct connection up to 100 A per phase;
- GSM/GPRS remote transmission;
- no PLC concentrator required;
- active and reactive energy measurement;
- four tariffs;
- RS-485 and optical port;
- AMR-system integration;
- IP54 enclosure;
- manufactured in Uzbekistan.
⚠️ Important: the letter G identifies the GSM/GPRS module. Remote transmission requires a SIM card, cellular coverage and correct server configuration.
