3-phase electricity meter | TE73 SP-2-3 | 380V 100A | PLC modem

⚡ 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;
