Articles and guides for this product
⚡ The TE73 SP-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 data through existing power wiring using a removable PLC module.
🔤 Model designation
- S — three-element four-wire version;
- P — removable PLC communication module;
- 2 — 10(100) A current rating;
- 3 — 230/400 V voltage rating.
The letter P identifies a PLC module. It is not a GSM modem, and no SIM card is installed inside the meter.
🔌 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.
🎯 Accuracy
- active energy — class 1.0;
- reactive energy — class 1.0;
- meter constant — 1000 imp/kWh;
- starting current — approximately 0.04 A.
📡 PLC communication
PLC transmits meter readings through existing mains wiring to a compatible concentrator.
Remote internet-based reading requires a PLC concentrator, compatible protocol, server software and meter registration in the AMR system.
🔗 Communication interfaces
- PLC over power wiring;
- RS-485 wired digital interface;
- optical port for local reading and configuration;
- GSM/GPRS is not included in the SP modification.
🕒 Multi-tariff operation
The meter supports at least four tariffs and can separate consumption by time period and day type.
💾 Memory and event records
Tariff readings, load profiles, daily and monthly values and event records are retained in non-volatile memory.
🚨 Monitored events
- meter or terminal-cover opening;
- power failure;
- reverse energy flow;
- power-limit violation;
- configuration changes;
- communication errors;
- 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 SP-2-3 electricity meter;
- removable PLC 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;
- PLC data transmission;
- no SIM card required;
- active and reactive energy measurement;
- four tariffs;
- RS-485 and optical port;
- AMR-system integration;
- IP54 protection;
- manufactured in Uzbekistan.
⚠️ Important: the existing Schetchik.uz description contains specifications for another version: 57.7/100 V and 1(6) A. The correct TE73 SP-2-3 values are 230/400 V and 10(100) A.
